Current Attempt in Progress

A $13\mathrm{.}6$ g wire of length $76\mathrm{.}8$ cm is suspended by a pair of flexible leads in a uniform magnetic field of magnitude $0\mathrm{.}458$ T $($see the figure$).$ What is the $($a$)$ magnitude and $($b$)$ direction $($left or right$)$ of the current required to remove the tension in the supporting leads?
