what is the motor effect
when a current carrying conductor is placed in a magnetic fiend it experiences a force
what is the motor effect caused by
the field created by the current interacting with the magnetic field
in what circumstance will the conductor not experience a force
if the conductor is parallel to the magnetic material
is has to be perpendicular
how can the force be increased
- increasing size of current
- increasing length of conductor (wire) in the magnetic field
- increasing flux density
how can the direction of the force be reversed
reversing the direction of the current or magnetic field
In Flemings left hand rule, what does the thumb, first finger and second finger represent
Thumb- direction of force (F)
First finger- magnetic field (B)
Second finger- current (I)
What does the motor effect convert electrical energy into?
Kinetic energy (movement), and in speakers, sound energy.
Which devices rely on the motor effect?
Loudspeakers, headphones, and electric motors.
