A square loop of wire consisting of a single turn is perpendicular to a uniform magnetic field. the square loop is then re-formed into a circular loop, which also consists of a single turn and is also perpendicular to the same magnetic field.

A thin cylindrical shell and a solid cylinder have the same mass and radius. The two are released side by side and roll down, without slipping, from the top of an inclined plane that is 1.8 m above the ground.
