A New Phenomenon
Equipment needed:
bolt with 2 washers and a nut
coil of #20 wire
battery board
6V lantern battery
penny, paper clip, scrap of paper, compass
multimeter
-
- Wrap a coil around a bolt. There is a sample at the front of the room.
-
- Now wire up a circuit consisting of a 6 volt battery, a switch, and your coil.
- What happens to your coil and bolt when the switch is turned on?
-
- Pick up a scrap of paper by touching it to the bolt.
- Try picking up a paper clip with the bolt. What happens?
- Try the same with a penny (or other coin). What are the results?
-
- Come up with an hypothesis (make a guess for a law) of what you have
observed.
-
- How would you test your law?
