ELECTROMAGNET Extra Practice
I can… describe some of the properties of magnets and some of the basic
behaviors of magnetic forces
I can…generate an electric current by passing a conductive wire through a
magnetic field and quantify electric current, using a galvanometer or multimeter.
Priti also did an experiment on an electromagnet. She wanted to see how the number
of turns in the coil affects the strength of the electromagnet. Here are her results.
Number of turns
10 20 30 40 50
Paperclips picked up
5
11 22 39 60
1. Plot Priti’s results as a line graph on
the graph paper to the right. Join
up the points with a smooth
curve.
2. The more turns in the coil …
(Select all that apply)
a. The more paperclips it picks up
b. The fewer paperclips it picks up
c. The weaker the electromagnet
d. The stronger the electromagnet
3. What advantage would there be for Priti to conduct the experiment more than
once?
4. What adjustments could Priti make to her experiment to pick up even more
paperclips?
5. Label the electromagnet components below:
o North Pole
o South Pole
o Direction of current (draw arrow)
o Iron Nail
o Insulated Wire Coil
o Battery (Power Source)
[EXTRA] Based on Priti’s experiment and your knowledge of electromagnets, design
an advertisement to sell an electromagnet to your friends. This could be an ad printed
in a magazine or something you would scroll past on Facebook. It’s your job to share
the benefits of an electromagnet!
