Magnetic lines of force |
These are the lines which are due to the magnetizing field and exist in air even when there is no mag netic substance in the field |
|
|
Lines of magnetization |
If a magnetic subs is kept in a magnetic field, it is magnetised by induction and these lines of force passing within the subs due to the magnetization are known as lines of magnetization |
|
|
Magnetic induction or magnetic flux density |
In any material the no. of lines of magnetic force passing through unit area perpendicularly is called magnetic induction. It's unit is Webber per metre square or tesla |
|
|
Bohr magneton |
The orbital magnetic moment of an electron in an atom can be expressed in terms of atomic unit of magnetic moment called Bohr magneton |
|
|
Magnetic field intensity |
At any point in the magnetic field the force experienced by an unit north pole placed at that point is called magnetic field intensity(H). It's unit is Ampere per metre |
|
|
Magnetic susceptibility |
It is defined as the ratio b/w intensity of magnetization (I) & the magnetic field intensity (H) |
|
|
Intensity of magnetization |
It is defined as magnetic moment per unit volume. It's unit is Ampere per metre |
|
|
Magnetic permeability |
It is defined as the ratio b/w magnetic flux density (B) and the magnetic field intensity (H). It is the measure of degree at which the lines of force can penetrate through the material. ( mu) |
|
|
Relative permeability |
It is the ratio between the permeability of medium (mu) to the permeability of free space (mu knot). |
