Topic 6 - The Motor Effect Flashcards
What happens when a current-carrying wire is put between magnetic poles?
The two magnetic fields affect one another, resulting in a force on the wire which can cause the wire to move.
Why does the motor effect happen?
Charged particles moving through a magnetic field will experience a force as long as they’re not moving parallel to the field lines
When would a wire not experience the motor effect?
If the wire runs along the magnetic field
What causes the magnitude of a force produced by the motor effect to increase?
The strength of the magnetic field increasing or the current passing through the conductor increasing
What happens to the force if you reverse the current/magnetic field?
The direction of the force reverses
What does Flemings left hand rule tell you?
Which way the force acts (motor effect)
What does each finger stand for in Flemings left hand rule?
First finger - field
Second finger - current
Thumb - force
