Magnetization technology refers to the use of a magnetic field to either:

Magnetize a substance

Change the bonding state and nature of the substance being magnetized

Change the state of atoms and electrons

Promote the chemical reaction of the substance and the combustion of the fuel

Change the crystal form or freezing point of the substance

Do Magnetic Rings Help with Weight Loss?

Magnetic devices abound among the no-diet-no-exercise weight loss aids.

Touted for its supposed effects on metabolism and circulation, magnetic rings, bracelets, or earrings are sold for the purposes of aiding weight loss.

There is, however, no evidence whatsoever as to the effectiveness of magnets in weight loss.

Proposed Mechanism of Action

The north pole of a magnet is supposed to stimulate metabolism, increasing the calories burned in cells and thus increasing the general energy expenditure.

In the rings -- marketed for wearing on fingers or toes depending on the design -- the magnets are used in combination with principles of acupressure.

Acupressure is an alternative therapy technique, based on the idea that stimulating certain points in the body will lead to changes in internal organs and physiological processes.

The general principles are the same as used in acupuncture.

Lack of Evidence

There is no evidence whatsoever that magnetic rings work for weight loss or weight maintenance.

A search of PubMed, a database of more than 23 million citations for biomedical literature, revealed no clinical trials involving magnetic rings, or for that matter bracelets, purported to treat obesity or aid weight loss.

There are some trials that show that acupuncture or acupressure treatments have some effect on weight loss, but the systematic review of such studies performed in 2009 showed that the quality of the trials that support the efficacy of these methods is generally poor.

Possible Mechanism of Action

And yet there are people who swear by the bracelets and rings and the way magnets helped them lose weight.

The best explanation for these results is a simple placebo effect.

Being aware of receiving treatment and believing in its effectiveness can be a powerful force in healing, especially when psychological and motivational factors are as important as they are with any behavior change such as weight loss.

10 Super-Helpful Ways to Use Magnets

Everyday items become even more useful with a little magnetic magic.

These small, powerful discs or strips (look for them in varying strengths at a craft store) excel at creating vertical storage and a safe space for tiny items.

Just remember to keep them away from kids who might swallow them as you try these ideas:

1. Secure a trash bag.

This trick works with metal wastebaskets: When you fold the trash bag over the top of the pail, affix it to the outside of the can with magnets.

2. Hold pins while sewing.

Sarah Jane's Craft Blog

Avoid a DIY disaster (hello, sharp pins all over the floor) by placing them in a dish doctored up with strong magnets.

Learn how to make this one at Sarah Jane's Craft Blog.

3. Corral paper clips.

Place a magnet in your desk drawer to keeps metallic clips in one spot.

4. Stick up kids' cups.

Adventures in Pinteresting

Rheannon at Adventures in Pinteresting came up with this genius idea to keep her kids from dirtying more than one glass each day.

She glued magnets onto cups so they could hover on the fridge above the water dispenser.

When her kids want a drink, they can quickly grab a cup and replace it for later when they're done.

5. Add removable pizzazz to a lampshade.

Twelve Oaks Manor

We love this creative idea from Angela at Twelve Oaks Manor.

Add magnets to the back of decorative flowers and use them to pretty up a bare lamp shade.

Then, easily remove them whenever you tire of the look.

6. Fix a drafty door.

To make sure your sliding door always closes completely, affix one magnet to the door, and another to the frame (check out the how-to in this video ).

7. Organize your makeup.

Glue magnets to your favorite palettes and stick them up on a magnetic board, as Margaret did at Janicki Photography.

This way, your countertop remains clear, but your makeup is still within easy reach.

8. Store aluminum foil and plastic wrap on the fridge.

It might not be the prettiest solution, but if you use these wraps often, consider placing small magnets inside the boxes.

Then, you can place them on your fridge and grab them in a flash.

9. Create a cute kitchen bin.

A Pretty Cool Life

Attach magnets onto vintage tins, like Cheryl at A Pretty Cool Life, to make fridge decor that also acts as an extra storage spot.

10. Keep tiny pieces nearby.

3 Tips for Safe Neodymium Magnet

Neodymium magnets are the strongest permanent magnets in the world.

While used in packaging and display industries frequently, these rare earth magnets also make cell phones vibrate, help turn turbines, and power MRI scanners.

1. Check Your Surroundings

Large neodymium magnets can attract one another, and other ferromagnetic materials, from far off distances.

Even small neodymium magnets will snap toward one another when they are inches apart.

While it may seem fun to watch magnets “fly,” the force with which they slam into one another can be very dangerous.

If your skin gets caught between two magnets attracting to one another, you can quickly get blood blisters or worse, depending on the size and strength of the magnets.

To prevent injury, review your workspace before you use the magnets.

Remember, that even if the magnets don’t hurt you, you could fall victim to tools, scissors, or other metal items that are pulled into their magnetic field and could possibly cause harm by traveling at a high rate of speed toward the magnet.

2. Use Caution When Handling

While neodymium magnets look strong and shiny, that exterior hides a weaker interior.

Rare earth magnets are typically made by “sintering.” In this process, the elements neodymium, iron, and boron are ground into a powder, placed in a mold, and heated.

As a result, if neodymium magnets are compromised—typically by hitting one another or being dropped—they can easily splinter into many sharp, jagged pieces, rendering them unusable and creating a potential source of injury.

Smaller neodymium magnets are generally sold in stacks, sometimes with small plastic spacers between the magnets to separate them with greater ease.

If you are trying to remove a magnet from the stack, use a sliding motion to get them apart, rather than trying to pull them apart.

You must ensure that you do not let them snap back, as they will want to, to prevent them from breaking or pinching you.

In addition, once very large neodymium magnets attract one another, it can be difficult to separate them without damage.

Fortunately, larger neodymium magnets should be packaged with some safety measures, like large spacers that will help to separate the magnets from one another.

Do your best to use larger magnets one at a time.

If two large magnets get stuck together, try using the edge of a table to help separate them: Let one magnet hang over the edge, and slowly and carefully, push down to slide them apart.

3. Store Neodymium Magnets Wisely

Neodymium magnet safety extends to when you’re not using them.

While you don’t have to worry about these powerful magnets messing with electronic devices in your offices, such as phones or computers, you can’t put them just anywhere.
