The “jumping ring” demonstration. If you wind a solenoidal coil around an iron core (the iron is there to beef up the magnetic field), ... Suppose a current I is flowing around a loop, when someone suddenly cuts the wire. The current drops “instantaneously” to zero ... A line charge λ is glued onto the rim of a wheel of radius b, which is then suspended horizontally, as shown
