Question

A circular loop carrying a current is replaced by an equivalent magnetic dipole. A point on the loop is in

(a) end-on position
(b) broadside-on position
(c) both
(d) none

Answer 1

(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.
