If you hold a sheet of copper in a strong permanent magnet, with the plane of the sheet perpendicular to the magnetic field, and quickly jerk it away, you will feel no magnetic force. you will experience a magnetic force opposing your action. any force you feel will be due mainly to iron impurities in the copper since copper itself is not magnetic. you will experience a magnetic force assisting your action.
