What does the N35, N40, N42, N45, N48, N50, N52 grade mean?
Neodymium magnets are graded by the maximum strength they can be magnetized to.
The higher the number the stronger the magnet is, however the higher the number
the more brittle/brothættur the magnet becomes as well.

Neodymium (chemical symbol Nd) is element 60 on the periodic table.
It is a rare earth metal and forms one of the Lanthanides series.
When added to Iron (Fe) and Boron (B) (chemical formula Nd14Fe21B)
the resultant magnets are the strongest magnets currently available.
Neodymium magnets are usually coated Nickel-Copper-Nickel plating to prevent the iron from rusting.
Neodymium magnets are made of a brittle material.
This is true for magnets large and small.
WARNING!!! Mjög sterkir –
Strong magnets should Keep away from
Ironware and some easily magnetized
iron products, such as monitors, bank cards,
computers, televisions, mobile phones and other.
Without parents supervised do not allow children to playing magnets as they
could get injured. Especially pay attention to the small magnets , please
place somewhere children can’t reach place.
