E. The further away the magnet from the tramp metal iron, the lower the magnetic field intensity induced on the tramp metal therefore, the stronger the magnet must be to remove it. The clearance distance is determined by the size of tramp metal. For larger tramp metal, a larger clearance distance is required.
