Solid and slotted copper plates swinging into a uniform magnetic field.
Two pendulums of identical dimensions and mass are suspended from rigid lightweight rods and released from rest from the same initial angle. Pendulum 1 has a solid copper plate at its swinging end, while Pendulum 2 has a copper plate with narrow vertical slots cut into it to form a comb-like structure. Both pendulums swing downward into a region containing a uniform magnetic field directed perpendicular to their plane of oscillation. Which pendulum experiences greater magnetic damping as it enters the magnetic field, and why?
