Just take an example, a copper solenoid(closed circuit connected to a voltmeter) is kept vertically on a table, and a strong bar magnet is passed near it approx 20 cm away, would there be any reading in the voltmeter ?
Is it necessary to pass magnet through solenoid in Faraday's law experiment. If not, then how much emf could be induced if a normal bar magnet crosses a copper wire solenoid from a distance of approx 1 meter.
