7.1 L9 Electromagnets Lab

7.1 Lesson 9 Uncover - Electromagnets Lab 💡🧲

1

Prediction: What do you think you would have to do to make a light bulb light up by using a magnet? You can use words and/or pictures in your explanation.

To complete the rest of this lab activity, open the PhET simulation on Faraday's Electromagnetic Lab: CLICK HERE

(Your simulator should look like this. There are five blue tabs you will use to experiment with electromagnetism today.)

Part 1: Bar Magnet
Use the first tab on the simulation to answer these questions.

1

Describe how the compass and the bar magnet interact in the simulation.

1

What does the magnetic field look like around the magnet?
What does the magnet field look like inside the magnet?
Use the Show Your Work image to draw the magnetic field.

Part 2: Pickup Coil
Use the second tab on the simulation to answer these questions.

1

When you move the magnet towards the coil, describe what happens inside the coil.

1

When you move the magnet away from the coil, describe what happens inside the coil.

1

Change the magnet strength to 20%. What happens to the light now when the magnet is moved toward the coil?

1

How can you make the light brighter? Explain what steps or changes you can make. Support your answer with a screenshot in Show your Work.

Part 3: Electromagnet
Use the third tab on the simulation to answer these questions.

1

Suggest two ways of how you can make the magnetic field strength weaker. Number your responses.

1

Suggest two ways of how you can make the magnetic field strength stronger. Number your responses.

1

What happens to the magnetic field if you reverse the direction of the battery?

1

What happens to the magnetic field if you change the voltage on the battery?

Part 4: Generator
Use the fifth tab on the simulation to answer these questions.

1

Open the water tap. You should see that the light stays on. Explain why the light bulb stays lit.

1

Suggest at least two ways you can make the light bulb brighter. Number your responses. Use a screenshot in Show Your Work to support your answer.

Part 5: Transformer
Use the fourth tab on the simulation to answer these questions.

1

Move the battery and coil towards the right quickly and stop. Describe what happen to the light bulb.

1

Suggest at least two ways you can make the light bulb brighter. Number your responses. Use a screenshot in Show Your Work to support your answer.

Part 6: Wrap Up/Summary
Complete a graphic organizer below, then watch an Edpuzzle on electromagnets.

1

How is a regular bar magnet similar to an electromagnet? How are these types of magnets different from each other?
Use the Show Your Work section to complete a Venn diagram about these types of magnets. Add at least 2 things to each section of the graphic organizer.
