Electromagnet

Vedclass · Answer

(A) An electromagnet is used in cranes to lift heavy loads like cars in junkyards. This is because an electromagnet can be turned on and off by controlling the electric current. When the current is switched on,the crane becomes magnetic and picks up the metal object. When the current is switched off,the magnetic field disappears,allowing the load to be released easily.
