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 ?
A. 4.4 × 10–3 tesla
B. 5.2 × 10–3 tesla
C. 3.4 × 10–3 tesla
D. 7.8 × 10–3 tesla
