motor effect

what is the flemings left hand rule

used to see the direction of force that wire contains current going through a magnetic field.

what are the thumb and two fingers represent

thumb- direction of force

first finger- magnetic field 

second finger- direction of current. 

define motor effect

when wire that contains a current goes through a magnetic field causing it to experience a force.

what things does a motor have

solenoid

magnet

split ring communicator

brush contacts

define DC motor

(Direct current motor) turns electrical energy into movement using direct current electricity.

define split ring commutator

part of DC motor that reverses the direction of current in the coil every half turn so it keeps spinning at the same direction. 

define brush contacts 

can bring current in and out from the coil.

what does an iron do in the motor 

strengthens magnetic field

what does coils do

allows current and force to make the motor spin

why are magnets used for the motor

create magnetic field (permenant)

define radial field

when magnetic field lines are perpendicular to coil
