**Laws of Magnetizing Force**

- Let us consider that the two magnet poles are placed in a medium.
- The m
_{1}and m_{2}is magnetic strength of the two poles, r is distance between them and µ is absolute permeability of the surrounding medium. The force ( F ) between them is

( 1 ) Directly proportional to product of their pole
strengths

F α m

_{1}m_{2}
( 2 ) Inversely proportional to square of distance between
two poles

F α ( 1 / r

^{2})
( 3 ) Inversely proportional to absolute permeability of the
surrounding medium

F α ( 1 / µ )

Therefore

F α m

_{1}m_{2}/ µr^{2}
F = k m

_{1}m_{2}/ µr^{2}
Where k = Constant

The value of k = 1 / 4π in the SI system

F = m

_{1}m_{2}/ 4π µr^{2 }( Where k = 1 / 4π )
F = m

_{1}m_{2}/ 4π µ_{0}µ_{r}r^{2}( Where µ = µ_{0}µ_{r })
F = m
_{1}m_{2} / 4π
µ_{0} µ_{r}r^{2} ….… ( 1 ) |

**Unit Magnetic Pole**

- Let us consider magnetic pole strength m
_{1}= m_{2}= m - Distance between two poles r = 1
- Force between two magnetic pole F = 1 / 4π
µ
_{0}

Putting above
value in the equation ( 1 )

1 / 4π µ

_{0}= m^{2}/ 4π µ_{0}
m

^{2}= 1
m = ± 1

- The unit
magnetic pole is defined as the two poles of opposite polarity having same mass
which when placed in air with a distance between them is 1 meter, with a force
of 1 / 4π µ
_{0}newtons.
