Q: Can these magnets be machined to size in a lathe without damaging the magnetic field?

Q: Is there a North and South Pole or one pole?

Every type of magnet has at least one North and South pole pairing. Some rare, specially designed or purpose magnets can have more than one pair of North and South poles and are known as multi-pole magnets. Without the flow of magnetic energy between the North and South poles, the...

Q: What is the life cycle of the magnetism in a magnet?

All magnets with the exception of Electromagnets are called Permanent Magnets. The magnetic field of Permanent Magnets which are made from mined mineral resources does not degrade with the passing of time under normal conditions. However, outside influence can certainly impact the magnetic properties of Permanent Magnets and can cause...

Q: How long does it take for the magnetism to lose its strength?

Neodymium magnets do not lose strength unless damaged or exposed to unfavourable conditions for long periods. Short periods of exposure to temperatures over 80℃ may cause a temporary loss of magnetic strength to Neodymium magnets but in many cases, the loss will be recovered. Most Neodymium magnetic products will remain...

Q: Which magnet is stronger - the N35 or the N50?

Frenergy specialises in supplying customers with an extensive range of super strong permanent Neodymium Magnets. We stock numerous types of these rare earth magnetic products including very small micro magnets as well as very large magnets. Neodymium magnets are the strongest magnets available and even some of our smallest magnets...
