Question

A point P is situated on the equator of short magnetic dipole of moment of $2A{m}^2$. If the distance of that point from its centre is 10 cm the magnetic potential at point P will be :

• A. $6\times {10}^{-5}J/Am$
• B. $3.5\times {10}^{-3}J/Am$
• C. $1.55\times {10}^{-6}J/Am$
• D. Zero

Answer 1

The correct option is D Zero

The magnetic potential at the equator of short magnet is equal to zero.

The correct option is D.
