Consider the following statements:
Statement A: Magnetic monopoles do not exist and therefore magnetic field lines form closed loops.
Statement B: A bar magnet makes an angle of \(30^\circ\) with a uniform magnetic field. If the maximum torque experienced by the magnet is \(3.464 \times 10^{-5}\,\text{Nm}\), the potential energy of the system is \(3 \times 10^{-5}\,\text{J}\).
Statement C: A superconductor is a perfect ferromagnetic material.
Show Hint
Superconductors exhibit perfect diamagnetism, not ferromagnetism (Meissner effect is key distinction).
