Electricity and Magnetism
2
What Do You Think?Using a T-Chart, write down
everything you know about electricity and
magnetism

• Magnetism

• Electricty

3
For You To Do, Part 1

• Touch the wires to the battery as shown in the
  picture, do not attach the wires to the battery.
• Place the compass in 3 positions along the wire
  and observe the interaction.

4
Please write

• Describe what happens to the compass as you move
  it along the wire?
• Describe what the compass is detecting.

5
Move the compass

• Move the compass to 3 positions around the wire
  (not touching it)
• Observe what is happening to the compass

6

• Describe what is happening to the compass now and
  how it is different from the compass movements
  when the wire was touching it.
• Describe what the compass is now detecting

7
For You To Do, Part 2

• Observe the pattern (if any) of the sprinkled
  iron filings on the overhead transparency.
• Write down what happens when the magnet is placed
  under the iron filings

8
For You To Do, Part 2, continued

• Draw a picture of the iron filings and the magnet
• Describe what the iron filings are detecting.
• Name what you have just described.

9
For You To Do, Part 3

• Using the supplies given (magnet, coil of wire,
  galvanometer), to create an electric current that
  can be measured with the galvanometer
• Draw your successful setup and explain in writing
  what happened
• Describe the relationship between a magnet and
  electricity

10
For You To Do, Part 4

• Using the supplies given (nail, wire, battery,
  paper clips), make a magnet
• Draw your successful setup and explain in writing
  what happened
• Describe the relationship between the battery
  (electricity) and the nail (magnetized)

11
For You to Do, Part 5

• Watch the demo of the balloon and the wall
• Watch the demo of the tape

12
What is happening on the atomic level?

• On the before picture draw 10 electrons on
  each object
• On the after picture draw the new location of
  these 20 electrons
