The conducting ring was placed in a magnetic field perpendicular to its plane.
Current I circulates through the ring. If the ring wire can withstand the
breaking load F, then at what magnetic field induction will the ring break?
Radius of the ring R. The effect of the magnetic field generated by current I
on the ring is ignored.
9.2 The magnetic field of a moving charge. Induction of the
magnetic field from a linear current
