There are no couple acting when two bar magnets are placed coaxially separated by a distance because

A

There are no forces on the poles

B

The forces are parallel and their lines of action do not coincide

C

The forces are perpendicular to each other

D

The forces act along the same line

Text Solution

Verified by Experts

The correct Answer is:
D
If magnets are placed coaxially, then theta=0
therefore Force acts a long the same line.
