MCQ
A circular loop carrying a current is replaced by an equivalent magnetic dipole. A point on the loop is in:
  • A
    End$-$on position.
  • Broadside$-$on position.
  • C
    Both.
  • D
    None.

Answer

Correct option: B.
Broadside$-$on position.


The position of the points lying on the equator of a magnetic dipole is called the broadside$-$on position. In our case, the point on the loop $($after replacement of the circular loop with an equivalent magnetic dipole$)$ lies on the equatorial position of the equivalent magnetic dipole. Hence, the point lies on the broadside$-$on position.
If $P$ was the point on the loop, then it is clear from the figure that point $P$ lies on the broadside$-$on position of the equivalent magnetic dipole.
