Two identical short bar magnets, each having magnetic moment `M`, are placed a distance of `2d` apart with axes perpendicular to each other in a horizontal plane. The magnetic induction at a point midway between them is

A

`mu_(0)/(4pi)*(sqrt2)M/d^(3)`

B

`mu_(0)/(4pi)*(sqrt3)M/d^(3)`

C

`mu_(0)/(4pi)*M/d^(3)`

D

`mu_(0)/(4pi)*(sqrt5)M/d^(3)`

Text Solution

Verified by Experts

The correct Answer is:
