Six s imilar magnetic poles are placed ...

Six s imilar magnetic poles are placed on six corners of a regular hexagon of side `10 cm`. A south pole of strength `10 Am` is placed at the centre of hexagon. Find the magnetic force on the south pole.

A

Zero

B

`4pixx10^(-4)N`

C

10 N

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
From force diagram shown in figure, the net magnetic force is zero. In general, if similar poles are placed on the corners of a regular polygon. Then, the net magnetic force on a pole placed at centre is zero.
