The circular top portion of the circuit in the image below lies in a uniform magnetic field of magnitude B and directed out of the plane of the screen. The loop is pulled as shown so that its area decreases. The decreased area is indicated by the dashed loop in the diagram below (the wires in the circuit remain connected for a complete closed circuit, but this is not explicitly shown on the diagram for clarity). The magnitude of the...
