# Tension Force In Ring

A current I=10A flows in a ring of radius r=15 cm made of very thin wire.The tensile strength of the wire is equal to T=1.5 N.The r=15 cm made of very thin wire.The ring is placed in a magnetic field which is perpendicular to the plane of the ring so that the forces tend to break the ring.Find B(in T) at which the ring is broken.
