Intensity of magnetisation
A permanent magnet in the shape of a thin cylinder of length has magnetisation .
Its magnetization current is
Here,
Then
Assume that each iron atom has a permanent magnetic moment equal to 2 Bohr magnetons ( 1 Bohr magneton ). The density of atoms in iron is atoms . Find the maximum magnetic moment per unit volume.
The total magnetic moment per unit volume.
Which of the following is not correct about relative magnetic permeability ?
It is a dimensionsless pure ratio.
For vacuum medium its value is one.
For ferromagnetic materials
For paramagnetic materials .
Relative magnetic permeability
It is a dimensionless pure ratio and for paramagnetic materials .
The ratio of intensity of magnetisation and magnetising field is called
permeability
magnetic intensity
magnetic susceptibility
If is absolute permeability of vacuum and is relative magnetic permeability of another
medium, then permeability of the medium is
The magnetic susceptibility is given by
The susceptibility of annealed iron at saturation is 5500 . Find the permeability of annealed
iron at saturation.
. A magnetising field of produces a magnetic flux density of in an iron rod.
The relative permeability of the rod will be
1
Since
If relative permeability of iron is 2000 . Its absolute permeability in S.I. units is
S.I. units
