Ceramic Magnet Strength Rating

Neodymium magnets will lose about 1 of their magnetic strength every 10 years due to self demagnetization.
Ceramic magnet strength rating. It is expressed in gauss or tesla 1 tesla 10 000 gauss. They are very. As with all magnet alloys ceramic magnets should not be used as structural elements. The magnetic field strength is a measurement of the magnetic field s strength and direction at a particular point near the magnet.
Often sacrificing space and using more ceramic ferrite magnet alloy is a very good trade off for the low cost. Composed of strontium carbonate and iron oxide ceramic ferrite magnets are medium in magnetic strength and can be used at fairly high temperatures. For every increase of 1 the magnet s strength increases by about 1. Ceramic magnets also known as ferrite magnets are part of the permanent magnet family and the lowest cost hard magnets available today.
If a magnet has a grade of n 42 it has a maximum energy product of 42 mgoe. In general the number indicates the strength of the magnet measured in megagauss oersted mgoe. Ceramic magnets have the lowest energy density of the commercially viable alloys but are by far the most cost effective. It depends on the size shape and grade of the magnet where the measurement is performed and the presence of any other magnets or ferromagnetic materials nearby.
For example an n 42 magnet is about 2 stronger than an n 40 magnet.
