Uses for our Rare Earth Cylinder Magnets:
These versatile Neodymium Cylinders can be used for a variety of applications thanks to their small but powerful magnetic pull. Measuring 4mm in diameter and 5mm in length, these small Rare Earth cylinders have a surprisingly strong pull force of over 1 kilogram. Their elegant and sleek appearance, coupled with their accuracy and precision, make them ideal for display purposes, arts and crafts, and as sensors in small motors. They are also known for their accuracy and efficiency when used in electronic devices such as microphones and speakers.

Copper Coated NdFeB Magnets Disc Shaped feature: Neodymium is a rare earth type of permanent magnet made from an alloy of neodymium, iron, and boron. Neo magnets are currently the strongest permanent magnets known. It is also one of the most abundant of the rare earth elements.
These magnets are cheaper, lighter, and stronger than samarium-cobalt magnets. However, neodymium magnets lose their magnetism at high temperatures. Samarium-cobalt magnets do not.
Neo tends to be vulnerable to corrosion similar to rusting, causing the magnet to weaken and eventually break down into a powder. This problem is solved by applying a protective coating. Nickel plating or nickel/copper/nickel plating is used as a standard method, although many other protective coatings are also in use.
It is not recommended to use the magnet without a protective layer. The application of the magnet will affect the choice of coating. For example gold plating is ideal for many medical applications, rubber coating provides additional friction, rubber coated zinc plating is used in marine environments, etc. Large Adhesive Knife Holder Magnet Wall-Mounted (No Drill Screws) – Size 24″

Neodymium magnets have replaced Alnico and ferrite magnets in many applications where strong permanent magnets are required. The greater strength allows the use of smaller, lighter magnets in many applications.  Double-Side Drill Mounting Knife Holder Magnet for Refrigerator – Size 22″
