Solution

The correct option is D $\frac{B}{2}$
Magnetic induction due to a short bar magnet on its axial line at a distance d is B. Find out its magnetic induction value at the same distance on the equatorial line The magnetic field for short bar magnet axial point is half the value of magnetic induction value at the same distance on the equatorial line .
$2 B_{e q} = B_{a x i a l} = B$
$B_{e q} = \frac{B}{2}$
