4. A piece of copper wire is formed into a single circular loop of radius 12 cm. A magnetic field is oriented parallel to the normal to the loop, and it increases from 0 to 0.6 T in a time of 0.45 s. The wire has resistance per unit length 3.3 x 102 S2/m. а. What is the total resistance of the wire? b. What is the change in magnetic flux through this wire loop? What is the induced emf in that loop? с. d. What is the current induced in that loop?
