Consider a magnetic dipole kept in the north to south direction. Let `P_1, P_2, Q_1, Q_3` be four points at the same distance from the dipole towareds north, south, east and west of the dipole respectively. The directions of the magnetic field due to the dipole are the same at

Options

A. `P_1` and `P_2`
B. `Q_1` and `Q_2`
C. (b) `P_1` and `Q_1`
D. `P_2` and `Q_2`.

Answer

A, B

Explanation

As is clear from figure, the direction of magnetic fields due to dipole are same at `(P_1, P_2)` and at `(Q_1, Q_2)`.
