 6 x 15 N38 Ni Neodymium Disc Magnet

Neodymium discs are strong magnet and are very useful for hanging or holding circular or disc shaped metal objects as well as a wide range of other magnetic applications.

Rare earth neodymium magnets, also known as NdFeB magnets or Neo magnets, are made from an alloy of neodymium, iron and boron. They have excellent magnetic property and are extremely strong for their small size. Neodymium magnets are permanent, and have a high maximum magnetic energy.

Pros and cons:

-Best power to weight ratio of all magnets.
-High resistance to demagnetization.
-Magnetism starts to decrease (and can be permanently lost) at 80°C. (This depends on the handling of magnets.)
-Low corrosion resistance. (If the plating is damaged)
-Will rust when exposed to wet elements.
-Brittle (May break, crack, or chip upon sudden collisions with other magnets or metals.)
-Drilling magnets causes magnet to shatter. (Do not drill magnets as friction can cause fire / explosion due to flammable material.)
-Often higher cost choice

Important warnings and tips for using magnets.

Please make sure you read and take care when using magnets.

How to separate magnets safely:

To separate magnets, use a sliding motion, never try pulling magnets apart as it will cause them to snap together causing injuries. If you have larger stronger magnets use a wooden table or desk and overhang one magnet. Apply strong downward pressure to separate magnet from the other magnets. Once separated, keep moving the magnet to a safe distance.

Magnets attract to each other, handle with care:

If two magnets are placed loosely apart, they could leap together unexpectedly, with extreme speed and force, which could shatter and break both the magnets and could injure your finger if it is caught in between. Flying chips are sharp and could be a danger to your eyes. Handle only one magnet at a time.

Nickel Allergies:

Some of our magnets have a nickel coating. Prolonged contact with skin may cause irritation.

Warning for children using magnets:

DO NOT allow children to play with magnets unsupervised and do not allow children to handle stronger magnets as they are powerful and will cause injury and could be fatal if swallowed. Magnets are not toys!

Magnetic Sensitive Items:

-Media: Keep away from credit cards and other magnetically stored media.

-Pacemakers: Keep magnets away from pacemakers. The operation of heart pacemakers may be affected by the proximity of a magnet. Magnets can set a pacemaker working in a way that is not suitable for the user and that might affect their health.
