Magnetic fields and friction

Friction is a force resisting relative movement of objects or fluids caused by the interactions taking place at the contact between the objects or fluids. Hence, by definition there cannot be friction between an object and magnetic field.

This does not mean though that there cannot be a force resisting movement of a metal object relative to magnetic field. You wouldn't call any such forces friction, though.

One kind of breaking force appears when a metal object moves relative to magnetic field and is caused by induction which produces eddy currents which in turn generate opposing magnetic field which resists the movement of the metal object. This is how eddy current brake works.
