Question 5.21: A magnetic dipole is under the influence of two magnetic fields. The angle between the field directions is 60º, and one of the fields has a magnitude of 1.2 × 10 −2 T. If the dipole comes to stable equilibrium at an angle of 15º with this field, what is the magnitude of the other field?Class 12 - Physics - Magnetism And Matter Magnetism And Matter Page-203 |

Answer» GIVEN , magnitude of magnetic field, B = 1.2 × 10^-2T angle between DIPOLE and field DIRECTION is 60° finally, dipole comes stable EQUILIBRIUM at an angle of 15° . magnetic dipole moment experiences torque due to both the field and is in equilibrium. e.g., so, 1.2 × 10^-2 × sin60° = |
