Question
A wire of length 60cm and mass 10kg is suspended by a pair of flexible leads in a magnetic field magnitude and direction of the current required to remove the tension in the supporting leads.

Hmmmm. Is the tension just from weight of the wire?
mg=magnetic force=I*L*B
so I*B=mg/Length
the direction of I depends on the direction of B.
mg=magnetic force=I*L*B
so I*B=mg/Length
the direction of I depends on the direction of B.
