WebThe Magnetic Vector Potential Due to a Spinning Ring of Charge. Find the magnetic vector potential everywhere in space due to a spinning charged ring with radius R R, total charge Q Q, and period T T. Evaluate your expression for the special case that →r r → is on the z z -axis. Far from the ring, in the plane of the ring. WebWhen the magnet moves closer to the coil the flux rapidly increases until the magnet is inside the coil. As it passes through the coil the magnetic flux through the coil begins to decrease. Consequently, the induced EMF is reversed. Exercise 1a: A small 10 mm diameter permanent magnet produces a field of 100 mT.
