What is the motor effect?
What is the motor effect?
Force on current-carrying wire in magnetic field
What does a current-carrying wire produce?
What does a current-carrying wire produce?
Its own magnetic field
What is the direction of force in motor effect?
What is the direction of force in motor effect?
Right angle to current direction and magnetic field
Angle for full force in motor effect
Angle for full force in motor effect
90 degrees (right angle) to magnetic field
Force when wire parallel to magnetic field
Force when wire parallel to magnetic field
No force
Force when wire not at 90° to magnetic field
Force when wire not at 90° to magnetic field
Less force than at 90 degrees
