A magnetic dipole is under the influence of two magnetic fields. The angle between the field directions is \[60{}^\circ \] and one of the fields has a magnitude of \[1.2\times {{10}^{-2}}T\]. If the dipole comes to stable equilibrium at an angle of \[15{}^\circ \] with this field, what is the magnitude of other field?

• A. \[4.4\times {{10}^{-3}}\,tesla\]
• B. \[5.2\times {{10}^{-3}}\,tesla\]
• C. \[3.4\times {{10}^{-3}}\,tesla\]
• D. \[7.8\times {{10}^{-3}}\,tesla\]
