What is the motor effect?

Force on a current-carrying wire in a magnetic field

What causes the motor effect?

Interaction between wire's magnetic field and external magnetic field

Wire placement in motor effect

Between N and S poles of magnets

Effect of field interaction on wire

Force pushes wire out of field

Direction of force in motor effect

Perpendicular to both current and field direction

Wire angle for maximum force

90∘90^\circ (perpendicular) to magnetic field

Force when wire not at 90∘90^\circ

Less than maximum force

Force when wire parallel to field

No force

What's needed to find force direction?

Magnetic field direction and current direction
