Common trap
motor-effect force direction: avoid motors and generators: Instead, identify the exact Unit 4.7 idea in Electromagnetism, then explain how it links to a loudspeaker coil moving in a magnetic field and the objective to describe how shaping a wire to form a solenoid increases the strength of the magnetic field created by a current.
