Explain why a magnetized iron bar dropped vertically through a hollow region of a thick cylindrical shell made of copper experiences a retarding force. 

Explain why a magnetized iron bar dropped vertically through a hollow region of a thick cylindrical shell made of copper experiences a retarding force. 

Magnetic flux linking the shell changes inducing eddy currents that oppose motion of the bar magnet thus causing retardation.
