Electromagnetic Induction Flashcards
1
Q
What is Electromagnetic Induction?
A
This is the production of a voltage in a wire that is experiencing a changing magnetic field. If the wire is part of a complete circuit a current flows.
2
Q
How do you make the voltage bigger?
A
- The number of turns on the coil is increased
- A stronger magnet is used
- The Speed if the Movement is increase
3
Q
What happens if the movement is reversed?
A
The Voltage and Current is also reversed
4
Q
If no movement or no field lines are cut, there is…
A
No Voltage
