A wire ABCDEF (with each side of length L) bent as shown in figure. The wire carrying a current I is placed in a uniform magnetic induction B parallel to the positive y-direction. The force experienced by the wire in the z-direction is

Text Solution

Verified by Experts

The correct Answer is:
ILB, positive z
ILB, Positive z
Net force is on an imaginary wire FA having current I from F to A
`vecf=I[(Lhati)xx(Bhatj)]=ILBhatK:'` Magnitude of force is ILB and direction of force is positive z.
