A charged particle with mass m and dipole moment u is kept fixed on the axis of a circular current loop of radius a, and current I, at a distance b from the center of the loop. I b Problem # 26 Z a) Find the force between the loop and the particle. Explain whether it is attractive or repulsive. b) The particle is now released to move along the loop axis. Find the kinetic energy if the particle reaches the center of the loop. c) The particle is now placed at the center of the loop. By using the definition of the dipole potential energy, describe the motion of the particle for small displacements from the center along the axis. What are the relevant physical quantities defining the particle's motion?
