Electricity and
Magnetism
What Do You Think?
Using a T-Chart, write down everything you
know about electricity and magnetism

Electricty

Magnetism
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.
Please write…
1.
2.
Describe what happens to the compass
as you move it along the wire?
Describe what the compass is detecting.
Move the compass


Move the compass to
3 positions around the
wire (not touching it)
Observe what is
happening to the
compass
3.
4.
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
For You To Do, Part 2

5.
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
For You To Do, Part 2, continued
6.
7.
8.
Draw a picture of the iron filings and the
magnet
Describe what the iron filings are
detecting.
Name what you have just described.
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
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)
For You to Do, Part 5


Watch the demo of the balloon and the wall
Watch the demo of the tape
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
