Q
Motor effect equation
A
F = libsinθ
Where:
F: force
L: length of the current-carrying conductor within the magnetic field (m)
I: current (A)
B: magnetic field strength (T)
θ: angle between conductor and magnetic field
5
Q

A
The conductor is perpendicular to the magnetic field lines
6
Q
Minimum force occurs when…
A
Conductor is parallel to the magnetic field lines
