What does remanence mean?

Remanence Br is a measurement for the magnetic induction or magnetic flux density that remains in the magnet after successful magnetisation. Simply said: the higher this value is, the "stronger" the magnet.

T (Tesla) is used as the unit of measurement for magnetic induction and, respectively, magnetic flux density. The unit of measurement previously used was G (Gauss). 1 Tesla = 10 000 Gauss.

You can find the remanence of our super magnets in the physical magnet data table.

Difference to iron

If you removed an external magnetic field from a piece of iron, most of its molecules would return to their old positions and the iron would remain only slightly magnetic. Thanks to its special crystal structure, the neodymium iron boron alloy, however, keeps a large part of its magnetisation indefinitely.
