The Motor Effect Flashcards
1
Q
What happens when a current flows through a wire?
A
A magnetic field is produced
2
Q
What 2 factors can increase the size of the force?
A
Increasing the strength of the magnetic field, increasing the size of the current
3
Q
When won’t a conductor experience a force in a magnetic field?
A
When it’s parallel to the magnetic field
4
Q
What 2 factors can reverse the direction of the force?
A
Either the direction of the current or direction of the magnetic field is reversed
5
Q
What’s the motor effect?
A
Electric current flows through a coil of wire that’s free to rotate between two opposite magnetic poles, it experiences a force and moves
