A student is investigating electromagnetic induction using a bar magnet and a solenoid connected to a sensitive voltmeter. In which of the following scenarios will the voltmeter record a non-zero reading?
The bar magnet is held stationary inside the stationary solenoid.
The bar magnet and the solenoid are both moved to the right at the same constant speed of 2 m/s2\text{ m/s}2 m/s.
The solenoid is moved towards the stationary bar magnet at a constant speed of 2 m/s2\text{ m/s}2 m/s.
Both the bar magnet and the solenoid are kept stationary, but the number of turns in the solenoid is doubled.
