Many materials have unpaired electron spins, and the majority of these materials are paramagnetic.

When the spins interact with each other in such a way that the spins align spontaneously, the materials are called ferromagnetic (what is often loosely termed as "magnetic").

Due to the way their regular crystalline atomic structure causes their spins to interact, some metals are (Ferro)magnetic when found in their natural states, as ores.

These include iron ore (magnetite or lodestone), cobalt, and nickel, as well as the rare earth metals gadolinium and dysprosium (when at a very low temperature).

Such naturally occurring (Ferro)magnets were used in the first experiments with magnetism.

Technology has since expanded the availability of magnetic materials to include various manmade products, all based, however, on naturally magnetic elements.

Not only do we have a collection of ceramic magnets but we also have a large range of Neodymium Magnets as well.

These magnets are very robust in relation to their size.

Popular with industries and hobbyists.

Neodymium magnets are used in a wide variety of applications.

From hard drives to headphones to loudspeakers these magnets have seen it all.

Ceramic Magnets or ferrite

Ceramic magnets, or ferrite, are made of a sintered composite of powdered iron oxide and barium/strontium carbonate ceramic.

Due to the low cost of the materials and manufacturing methods, inexpensive Ceramic magnets (or nonmagnetized ferromagnetic cores, for use in electronic components such as radio antennas, for example) of various shapes can be easily mass-produced.

The resulting Ceramic magnets are noncorroding, but brittle and must be treated like other ceramics.

Neodymium-iron-boron (NIB)

Neodymium magnets also referred to as neodymium-iron-boron (NdFeB) magnets, have the highest magnetic field strength, but are inferior to samarium cobalt in resistance to oxidation and temperature.

This type of magnet has traditionally been expensive, due to both the cost of raw materials and licensing of the patents involved.

This high cost limited their use to applications where such high strengths from a compact magnet are critical.

The use of protective surface treatments such as gold, nickel, zinc, and tin plating and epoxy resin coating can provide corrosion protection where required.

Beginning in the 1980s, NIB magnets have increasingly become less expensive.

Even tiny neodymium magnets are very powerful and have important safety considerations. At Applied Magnets you will get the best possible price on these Neodymium magnets.

All you have to do is just browse and choose from our huge selection and we will do the rest.

Plus with shopping online you get the modern convenience of buying from your home or place of business.

Nonetheless, our neodymium magnets come in many different shapes and sizes.

From blocks, cubes, spheres, cylinders to arcs and rings;

we here on our website offer it all.

We can supply you with our neodymium magnets better than the other suppliers out there.

Magnet Safety

Place two magnets close to each other, even small ones, and they will attract, leap towards each other with great acceleration and then slam together.

Many of the magnets we supply are made from neodymium;

this means they are among the strongest magnets in the world and the force at which they attract to steel and each other can cause serious injury if necessary safety precautions are not followed.

It is easy to get caught out by magnets and lack of concentration is the single biggest cause of injury when handling magnets.

Always wear safety goggles when handling large magnets.

Always wear gloves when handling magnets to prevent pinching.

Children should NEVER be allowed to play with NEODYMIUM magnets.

Keep magnets at least 20cm away from sensitive electronic and storage devices.

Children

Children should NEVER be allowed to play with NEODYMIUM magnets.

Even relatively small magnets can cause blood blisters and cuts and tiny magnets can cause serious injury if swallowed.

If more than one magnet is swallowed, they can attract each other through the walls of the intestines, get stuck, and pinch the digestive tract causing major swelling and even life-threatening injuries requiring surgery.

Always keep all neodymium magnets out of the reach of children.

Crushing, cuts, and blisters

Fingers can quickly become caught between magnets causing blood blisters or cuts.

Wear gloves when handling larger magnets and always handle with care.

Larger magnets (30 cm3+) can easily crush fingers and break bones.

Breaking and chipping

Magnets slamming together is the most common cause of broken magnets and it is possible that one or both magnets could chip or shatter.

Due to the force exerted by the magnets, it is possible that chips may fly off at high speed into someone's eye, therefore we advise that when handling more than one neodymium magnet that you wear eye protection.

Chips and broken magnets can also be quite sharp, so treat them as carefully as you would broken glass.

Electronics

Always keep a safe distance (at least 10cm) between magnets and all objects that can be damaged by magnetism and remember, neodymium magnets are ten times stronger than ‘ordinary’ magnets! Items such as mechanical watches, heart pacemakers, CRT monitors and televisions, credit cards, diskettes, and other magnetically stored media such as videotapes are all affected by powerful magnets.

Separating

It is five times easier to slide a magnet from a ferrous surface than pull it off vertically.

Small magnets can usually be separated by hand by sliding one from the other using a sideways motion.

If you are unable to do this with your hands alone then a good tactic is to place the two magnets overhanging the edge of a desk or table and slide one vertically downwards.

Once separated, keep the free magnet moving away until a safe distance from the other(s) to avoid them snapping back together.

For really large magnets you will need a device known as a magnet splitter or separator jig.

These devices come in various forms but the component which is consistent across all designs is a non-magnetic handle that is used to push one magnet from the other.

For more advice about how to separate magnets, please read our ' how to separate magnets safely ' article.

HEALTH

The raw materials that our magnets are made from are not detrimental to peoples’ health.

However, it is important to recognize that magnets can have a dangerous effect on medical implants such as pacemakers.

Also, it is quite common for some people to suffer nickel allergies, usually triggered by wearing of jewelry.

As most of our neodymium magnets are coated with nickel, we offer the below advice.

Pacemakers

There is a general lack of understanding regarding how magnets can affect heart pacemakers and implanted heart defibrillators.

At ALBmagnets.com we sought advice from a specialist and the following information represents our best knowledge regarding how heart pacemakers are affected by magnets.

Lindsay Grant (BSc CEng FIET CSci FIPEM ARCP) is a Consultant Clinical Scientist and Head of the Clinical Engineering Department of Medical Physics & Bioengineering at the Royal United Hospital.

Lindsay kindly gave us this advice: “The operation of heart pacemakers will be affected by the close proximity of a magnet.

Magnets can set a pacemaker working in a way that is not suitable for the pacemaker user and that might affect their health.

This change will stop when the magnet is removed.”

She added: “The background to this is that magnets are used to put pacemakers into a mode of working that does not respond to the patient's own heart rhythm.

We regularly use magnet.

Magnets are metallic composites, usually ferrous metal composites, which produce a “magnetic field”;

the magnetic field causes other magnetic objects to be attracted to the magnet while other magnets are either attracted or repelled.

There are many different types of magnets all with different magnetic strength, heat resistance, corrosion tolerance, and permanence.

Magnets can largely be broken up into two categories: non-permanent and permanent;

non-permanent magnets are electromagnets which require an external source of power and are triggered electrically to be magnetic.

Electromagnets have many industrial applications such as solenoid valves, AC and DC motors, biomagnetic separation, transformers, and so on.

Permanent magnets include ceramic magnets (also known as ferrite magnets), alnico magnets and rare earth magnets.

For instance, magnetic ceramic products have lower magnetic power and are more brittle and easily breakable than some other magnets, but they are much more cost-effective and are used in non-structural applications in motors, magnetic chucks, and magnetic tools.

Rare earth magnets, on the other hand, are less cost-effective to manufacture but are far more powerful and retain their magnetism better than ferrite magnets;

they are used as industrial magnets for holding and lifting, motors, speakers and sensors, testing and MRIs.

Magnetic assemblies are tools or systems which use electromagnets, ceramic magnets, alnico magnets, rare earth magnets or a combination to do specific kinds of lifting, holding or separating of metallic materials.

Combinations of different magnets in assemblies can increase the overall magnetic force of the tool.

Most magnetic assemblies used in industrial and metal manufacturing use permanent industrial magnets to do various kinds of physical work, including metal parts and sheet metal lifting, mounting and holding, separating, and water treatment.

Permanent and nonpermanent (electromagnetic) magnet assemblies are used in automotive, aerospace, electronics and biomedical fields in beam control, film and software disk programming and erasing, Magnetic Resonance Imaging (MRI), sound speakers, sensors, TV monitors, welding equipment, power meters, ignition timing systems, linear actuators, blood testing and separating, electric motor activation and more.

Many types of magnets are specifically used for certain industries and applications.

For example, sheet magnets are a flexible ferrite-plastic composite that is extruded into magnetic sheets and used in automotive and consumer industries and can be cut into magnetic strips of rubber material.

Bar magnets are the most common type of magnet used today and are made from a ferrite metal material.

The most important properties magnet manufacturers consider during fabrication are porosity, ease of fabrication, magnetic retention under heat and corrosion, magnetic strength, and cost.

There is not one magical type of magnet that will have all of these characteristics, and different types of permanent magnets are made from various composites and therefore have very different properties and applications.

Ceramic magnets are sintered powder composites of ceramic powder, iron oxide, and either strontium or barium.
