Challenge Problems
Push your limits with challenges.
Question 1
A magnetic dipole with a magnetic moment of 3 AΒ·mΒ² 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?
π‘ Hint: Apply the torque formula while ensuring to assess (sin 60Β°).
Question 2
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 AΒ·mΒ², calculate the potential energy.
π‘ Hint: Remember to evaluate cos(120Β°) correctly for negative angles.
