Building an Electromagnet Worksheet Answers

1. Draw the battery, wire coil and magnetic fi

eld. Label the positive and negative ends of the battery, and the poles of the coil's magnetic field.

Diagram should look like this

Students can use arrows for the magnetic fiel

2. Describe what happens if you hold a nail or paper clip near the coil.

The object vibrates, or gets pulled in

to the coil.

3. Reverse the connection of the coil. Draw the battery, coil and magnetic field. Label the

positive and negative ends of the battery, and the poles of the coil's magnetic field. Physical objects are the same, but the magnetic field has a reversed polarity - the poles are switched.

4. Describe what happens if you hold a nail or paper clip near the coil.

The object vibrates, or gets pulled into the coil.

5. How did you test the strength of your electromagnet?

Answers will vary; check individually.

6. Can your electromagnet pick up paper clips when the current is disconnected?

Magnetism: Lesso

n 2, Building an Electromagnet Activity - Worksheet Answers 1

Electromagnet Engineering

7. What did you modify in building your electromagnet (number of coils or size of battery)?

Answers will vary.

8. Fill in the table below with how many paper clips your electromagnet was able to pick up.

Electromagnet How Many Paperclips Did It Pick Up?

With 10-12 coils

Answers will vary.

With fewer coils

How many coils? _________

With more coils

How many coils? _________

With a different battery #1

What size battery? _________

With a different battery #2

What size battery? _________

9. Write a sentence about how changing the number of coils or battery size affects how many

paper clips the electromagnet could pick up. While answers will vary, in general, students should show an understanding that more coils and/or a larger battery increases magnetic force, as shown by being able to pick up more paper clips.

10. What are some ways that engineers might be able to use electromagnets?

Answers will vary. Engineers use electromagnets to create motors, which are found in everyday use in cars, appliances, clocks and computers.
