1) using electricity and magnetism to move things.
- magnetic fields
running current through a wire - wire moves back, out of magnetic field
changing the current direction - wire moves forward, out of magnetic field
changing the magnetic field direction - will move the the opposite way it did when changing the current
increase the current (voltage) - the wire moves further and faster
increase the magnetic field strength - there is more motion
a wire in a magnetic field feels a force and moves
magnetic fields have a direction and a strength
- the motor effect
electric currents produce magnetic fields
current flows through the wire - magnetic field is formed
current through a wire - in a magnetic field - fields interact - wire feels…
