Electromagnetic Induction Flashcards
1
Q
Electromagnetic induction
A
Is the creation of the voltage and maybe a current in a wire which is experiencing a change in magnetic field
2
Q
How can you do electromagneticInduction
A
Use the Dynamo effect
An electrical conductor moves through a magnetic field
A magnetic field through an electrical conductor changes
During the Dynamo effect to get a bigger voltage you can change the strength of the magnet the speed of the movement and the number of turns on the coil
3
Q
AC generators
A
coil spins current is induced current changes Direction every half turn
Slip rings and brushes so contacts don’t swap
