Electric Motors And Electromagnetic Induction Flashcards
Flemings left hand rule
Thumb - motion (force)
Pointing finger - magnetic field (N to S)
Swearing finger - current
Movement from electricity
A charged particle moving through a magnetic field will experience a force
To increase the rate at which a motor turns…
Increase the number of turns (make a coil)
Increase magnetic field strength
Increase current strength
Process of how electricity is delivered to our homes (3)
Immediately after generation, the current is passed through a step up transformer
Here the voltage is increased and the Current is reduced
Close to where the energy is needed, the supply is passed down a step down transformer and the current is increased while the voltage is decreased
