The Motor Effect Flashcards
1
Q
What is the magnetic flux density?
A
How many field lines there are in a region
2
Q
What is the motor effect?
A
When a current-carrying wire is put between magnetic poles, the magnetic field around the wire interacts with the magnetic field. this causes the magnet to exert force
3
Q
How do you experience the full force from the wire?
A
The wire has to be at 90º
4
Q
What angle does the force act to the magnetic fields?
A
right angles
5
Q
How can you work out the size of the force?
A
Force = Magnetic Flux Density x Current x Length
F=BI1
