An aluminium cylinder rotates as it falls through a uniform magnetic field. Let it be falling in the y direction and the field direction be z. When its axis of rotation is perpendicular to the field direction (along the x axis), it slows down. When it is parallel to the field direction there is no braking.

If a large conductive metallic object is moved through a magnetic field which intersects perpendicularly to it, the magnetic field will induce small "rings" of current which will actually create internal magnetic fields opposing ...
An aluminium cylinder rotating through a uniform magnetic field is determined. The direction of the field rotation is provided.
