Blog – Magnetic ALPHABET

blog creative all about magnets

Everything you need to know about magnets – for the right selection and effective use.

The steel is shaded by a strong magnetic field. Mumetal deflects the last of the power lines.

How to shield the magnetic field

Can the magnetic field be shaded so that the magnet attracts from only one side? How to make two magnets stop attracting or repelling each other? Do you need to protect a sensitive device from the effects of magnetic fields?

Physical properties of neodymium magnets

Neodymium magnets are made from a compound of neodymium, iron and boron Nd2Fe14B. This material is characterized by very high remanence and maximum energy product, making them the strongest type of magnets in the world. The weakness of neodymium magnets are their low temperature resistance and brittleness.

Magnetic calculator

Calculate the strength and other data of a neodymium magnet. Just choose its shape, dimensions and material. Our calculator uses a combination of experimental measurements and theoretical physics to calculate the breakaway force, the magnetic field strength at the surface, and other parameters of a neodymium magnet as accurately as possible.

Which surface treatment to choose?

All neodymium magnets must be covered with a layer of protective material. The NdFeB material reacts with oxygen in the air and the bare magnet would gradually chemically decompose (rust). Which surface treatment is best for you? In addition to nickel, there are various other options: zinc, chrome, gold, epoxy resin, rubber or plastic.
