Charged particles in a uniform magnetic field
A clever animation showing the motion of charged particles in a uniform magnetic field
Magnet floating on a spinning aluminium disc as an example of Lenz's Law
current carrying conductor in a magnetic field experiences a force
Not the best production but a very clear explanation of the eddy currents that cause a magnet to fall slowly in a copper pipe.
