Just for fun now, see if you can make a sketch of this graph....
A small bar magnet, north pole down, is held 0.5 meter above the
]center of a vertical air core solenoid. The solonoid is 0.5 meter
long and sufficiently wide to allow the bar magnet to fall through
without touching its coils. A voltmeter (or an oscilloscope) is
attached to the ends of the solenoid coils.
Sketch a voltage vs time graph from the time that the magnet is
released, falls freely through the solenoid and emerges 0.5
meter below the solenoid bottom.
