The Generator Effect Flashcards
The Generator Effect
This occurs when a wire that has been bent into a coil shape/circuit is moved through a magnetic field which will induce a potential difference/current in the wire. This potential difference/current occurs due to the change in the magnetic field for the wire as it moves through it.
Once the wire/circuit stops moving, what will happen? And why does this happen?
Whenever the wire stops moving, the potential difference/current will disappear. This happens because the magnetic field is not changing.
What happens to the direction of the potential difference/current when the wire/circuit every time we change direction going into the magnetic field?
The potential difference/current will swap directions.
How can we recreate the generator effect without moving the wire/circuit?
Instead of moving the wire/circuit, we will move the magnetic field itself. There will still be changes in the magnetic field so a current/potential difference will be induced.
3 ways we can increase the strength of the induced potential difference?
- Increase the strength of the magnetic field
- Move the wire or magnets more quickly
- Shape the wire into a solenoid. The more turns it has
the more the potential difference
What does this effect also applies to what?
Moving a single magnet into and out of a solenoid.
