A loosely wound helix made of stiff metal wire is mounted vertically with the lower end just touching the mercury in a dish. When the current from a batter is started in the metal wire through the mercury, the wire executes oscillatory motion with the lower end jumping out of and into the mercury. Explain.

(A) : A loosely wound helix made of stiff wire is suspended vertically with the lower end just touching a dish of mercury. When a current is passed through the wire, the helical wire, the helical wire executes oscillatory motion with the lower end jumping out of and into the mercury. (R) : Like current carrying wires attract each other.
