Faraday's Law SIM

In the simulation above, you can see a metal coil and a magnet. To visualize the magnetic field, check the "Field lines" box in the left lower corner.

The Faraday's Law of Induction states that the changing magnetic field generates electric current. The process is investigated in this simulation. Before the next section, try to move the magnet up/down and right/left.

Observe the bulb and the voltmeter. When you know how to move the magnet, you are ready for a structured observation. Follow the instruction below. Take notes of your observations.

1A. Moving the magnet toward and away from the metal coil (NS)

1B. Moving the magnet toward and away from the metal coil (SN)

Let the magnetic north pole be on the left.

In order to change the poles, use the switch button:

Repeat all the observations listed in points above. Take notes of your observations.

2. Moving the magnet up and down near the metal coil.

3. Moving the magnet toward and away from the metal coil of various numbers of turns

Use the double coil button to switch to the two-coils view.

3A. Move the magnet toward and away from the four (4) turns coil. What happens with he bulb? Does it light? What does the voltmeter show? Take notes of your observations.

3B. Move the magnet toward and away from the two (2) turns coil. Is there any observable difference in the bulb's light as comparing to the longer coil? What does the voltmeter show? Take notes of your observations.

Type the conclusions based on your observations. Submit your answers.
