A magnetic dipole with a magnetic moment of 3 A·m² lies in a uniform magnetic field of strength 0.4 T. What is the torque acting on the dipole when it is tilted at an angle of 60 degrees?
💡 Hint: Apply the torque formula while ensuring to assess (sin 60°).
Consider the magnetic potential energy of a dipole when it is positioned at 120 degrees relative to a uniform magnetic field of 0.5 T. If its magnetic moment is 2 A·m², calculate the potential energy.
💡 Hint: Remember to evaluate cos(120°) correctly for negative angles.
