Question

A magnetic dipole is under the influence of two magnetic fields The angle between the field directions is 60° 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 15° with this field, what is the magnitude of other field?

Options

• 4.4 × 10^–3 tesla

• 5.2 × 10^–3 tesla

• 3.4 × 10^–3 tesla

• 7.8 × 10^–3 tesla

Answer 1

4.4 × 10^–3 tesla
