Explain Electromagnetic Induction Practice Test

A single loop of wire lies flat on a table. A uniform magnetic field points straight upward (perpendicular to the loop). Which action will definitely induce an EMF in the loop?

In a classroom demo, a 200-turn coil is connected to a galvanometer. A bar magnet is moved along the coil’s axis: first pushed into the coil, then held still inside it, then pulled out. During which part(s) will the galvanometer show a nonzero deflection (induced current)?
