MCQ
A circular loop carrying a current is replaced by ann equivalent magnetic dipole. A point on the axis of the loop is in:
- ✓End$-$on position.
- BBroadside$-$on position.
- CBoth.
- DNone.
✓
Answer
Correct option: A.
End$-$on position.
Points lying on the axis of a magnet are called end$-$on points. In our case, the point on the axis of the loop $($on replacing the circular loop with an equivalent magnetic dipole$)$ lies on the axis of the magnetic dipole or on the end$-$on position.
If P was the point on the axis of the loop, then it is clear from the figure that $P$ lies on the end$-$on position of the equivalent magnetic dipole.
