A straight wire of length `L` is bent into a semicircle. It is moved in a uniform magnetic field with speed `v` with diameter perpendicular to the field. The induced emf between the ends of the wire is

A long straight wire of length of length l is moving within a uniform magnetic field B With a velocity v perpendicular to the field . How much e.m.f. will induced?

A copper wire bent in the shape of a semicircle of radius r translates in its plane with a constant velocity v. A uniform magnetic field B exists in the direction perpendicular to the plane of the wire. Find the emf induced between the ends of the wire if (a) the velocity is perpendicular ot the diameter joining free ends, (b) the velocity is parallel to this diameter.
