This is due to the electromagnets used on cranes.
An electromagnet is a soft metal core made into a magnet by the passage of electric current through a coil surrounding it.Electromagnets are based on the magnetic effect of current and electromagnets show magnetic properties only as long as the electric current flows through the coil. These are temporary magnets. These are of very high strength and can be made easily. These are used on cranes for lifting heavy loads.
