Q6. A student moves a coil towards a magnet and sees an induced voltage on the voltmeter. What would she notice about the induced voltage if: [3] a. She moved the magnet towards the coil at a slower speed?



b. She moved the magnet towards the coil at the same speed?



c. She turned the magnet round and moved it towards the coil?

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?
