Q
Formula for calculating the magnetic permeability of a material
A
u=u0*ur
u0= permeability in a vacuum
ur= relative permeability
2
Q
If the relative permeability of a material is <1, what does that say about the material?
A
It is diamagnetic
3
Q
If the relative permeability of a material is >1, what does that say about the material?
A
It si paramagnetic
4
Q
