A loop of wire sits in a uniform magnetic field, everywhere
pointing toward you. Due to a changing magnetic flux through the
loop, an induced current flows in the wire, clockwise as shown. The
area of the loop is 1.94 m2, and the magnetic field initially has
magnitude 0.48 T.

E16D.1 Consider a circular loop of radius R that is expand- ing at a rate of dR/dt in a static and uniform magnetic field B that is perpendicular to the loop's face. Since the mag- netic field is static and uniform in every frame of reference, Faraday's law ХЕ + дв/at 0 tells us that the electric field in any frame in this situation must have zero curl and therefore cannot drive a current around the loop. (a) At a...
