- Metal ring Iron core Circle the appropriate response in each blank to explain why the ring jumps upward when the circuit is closed. Switch Coil 1. When the switch is closed, a current runs through the solenoid and creates a magnetic field pointing (up / down / no field). Battery 2. This causes the flux through the ring to (increase / decrease / remain the same). 3. As a result, (a clockwise / a counterclockwise / no) current is induced in the ring. 4. The induced current creates an induced magnetic field that points (upward / downward / no magnetic field). 5. The solenoid and the ring act like magnets and (attract / repel / do nothing), causing the ring to jump upward.
