Calculate the induced electric field (in V/m) in a 42-turn coll with a diameter of 17 cm that is placed in a spatially uniform magnetic field of magnitude 0.55 T so that the face of the coll and the magnetic field are perpendicular. This magnetic field is reduced to zero in 0.10 seconds. Assume that the magnetic field is cylindrically symmetric with respect to the central axis of the coll. (Enter the magnitude.) V/m

Problem 2 Show that in a current-free volume of space, a static magnetic field can never have a local maximum by considering V(B· B) · da, where S is the surface of a small volume V containing a point P in space.

Q1: What current density would produce the vector potential, Ã = k r ê (where k is a constant), in spherical coordinates. Q2: Find the magnetic field at the centre of an Equilateral triangle loop which carries a steady current I. Let R be the distance from centre to side.
