In general the number indicates the strength of the magnet measured in megagauss oersted mgoe.
Ceramic magnet strength rating.
Composed of strontium carbonate and iron oxide ceramic ferrite magnets are medium in magnetic strength and can be used at fairly high temperatures.
Ceramic magnets also known as ferrite magnets are part of the permanent magnet family and the lowest cost hard magnets available today.
Relatively high in magnetic strength and exhibiting good resistance to demagnetization ceramic magnets are popular for many consumer applications.
Often sacrificing space and using more ceramic ferrite magnet alloy is a very good trade off for the low cost.
Ceramic ferrite magnets are composed of barium or strontium ferrite and the most widely used lowest cost magnet material available today.
Neodymium magnets will lose about 1 of their magnetic strength every 10 years due to self demagnetization.
They are very.
For example an n 42 magnet is about 2 stronger than an n 40 magnet.
If a magnet has a grade of n 42 it has a maximum energy product of 42 mgoe.
Bhmax mgoe maximum energy product measured in mega gauss oersteds this is a direct measurement of a materials maximum magnetic strength after the magnet is fully saturated charged by an external magnetic field.
It is expressed in gauss or tesla 1 tesla 10 000 gauss.
The magnetic field strength is a measurement of the magnetic field s strength and direction at a particular point near the magnet.
For every increase of 1 the magnet s strength increases by about 1.
