Converts electrical enery to motion

Electric motor

15

Ferromagnetic properties of an iron core to efficiently raise or lower AC voltages

Transformer

16

Induced current in the coil produces a magnetic field to oppose the change in magnetic field which produced it

Lenz law

17

Proposed changing magnetic field can make an electric field and vice versa

James Clark Maxwell

Flux came from a latin word _______ and _______ means to flow

"Fluxus"
"Fluere"

20

SI unit for magnetic flux

Weber (Wb) - volts second

21

Arranging wire in a coil and running current produce field that is a bar magnet

Electromagnet
