Figure shows a wire AB of mass m placed on a rough inclined plane of inclination `alpha` and static friction coefficient `mu`. The wire carries a current I. Find the minimum magnitude of magnetic induction required to slide the wire up the inclined plane if direction of magnetic induction is normal to plane as shown in figure.

Text Solution
