A high-intensity searchlight uses a heavy-duty copper solenoid as part of its electromagnetic shutter system. During prolonged operation, the solenoid's copper windings become significantly warm.
Explain, in terms of charge carriers and the metallic lattice, why the temperature of these windings increases.
