Question

force between two magnetic poles is equal to
​

Answer 1

Answer:

The force between two magnetic poles may be expressed as follows: F = A M 1 M 2 r 2 , where F is the force; A is the constant, generally unity; M1, M2 are strengths of the respective poles; and r is the distance between the poles. Magnetic field strength is measured either in gammas or in oersteds.
