Question

What is the force while two poles of strength 200 and 180 CGS units are placed at a
distance of 60 cm apart?​

Answer 1

Hello Dear,

◆ Answer -

F = 10 dyne

◆ Explaination -

# Given -

m1 = 200 unit pole

m2 = 180 unit pole

r = 60 cm

# Solution -

Magnetic force between two poles is calculated by -

F = (μ/4π) m1.m2/r^2

F = 1 × 200 × 180 / 60^2

F = 10 dyne

Therefore, force of magnetism between 2 poles is 10 dyne.

Thanks dear...
