A wire of length \( L_{0} \) and mass \( m \) is suspended by a pair of springs in a magnetic field of induction \( \mathrm{B}_{0} \). The magnitude and direction of the current required to remove the tension in the supporting springs is
(1) \( \frac{2 m g}{L_{0} B_{0}} \) from \( P \) to \( Q \)
(2) \( \frac{m g}{L_{0} B_{0}} \) from \( P \) to \( Q \)
(3) \( \frac{2 m g}{L_{0} B_{0}} \) from \( Q \) to \( P \)
(4) \( \frac{m g}{L_{0} B_{0}} \) from \( Q \) to \( P \)
