describes about the production of electromagnetic induction and its applications

1. Can show this with presentation galvanometer, single wire, and large magnet.
Very weak signal.

2. Connect large coil to demo galvanometer. Move large magnet near the coil;
move coil near large magnet. Pass-around box with coil, bar magnet, and
galvanometer.

3. Bring small generator, similar to the one pictured (one in stock room, another
in 2B lab)

4. Set this up in a pass-around box using St. Louis motor (many in Phys 1 lab)
and galvanometer.

5. Just like it’s shown. Point out that the ring becomes hot.

6. Use big St. Louis motor and lawnmower battery

7. St. Louis motor in a pass-around box (with battery and switch).

8. Use big St. Louis motor and lawnmower battery

9. Just like it’s shown. Point out that the ring becomes hot.

10. Use large, strong magnet or rare earth magnets passed over a piece of
copper. Can drop rare earth down aluminum pipe.

11. Connect lawnmower battery to large electromagnet coil using a switch. Large
spark when switch opened.
