The oscillation period of a freely suspended magnetic needle does NOT depend upon: |
dimensions and mass of needle dipole moment of needle horizontal component of Earth's field length of suspension fibre |
length of suspension fibre |
The correct answer is Option (4) → length of suspension fibre The time period of oscillations of freely suspended magnetic needle is, $T=2\pi\sqrt{\frac{I}{MH}}$ Hence, it is independent of length of suspension fiber. |
