Current-carrying conductor in magnetic field experiences force
F=BIlF = BIlF=BIl
Magnetic flux density (tesla, T)
Current flowing through conductor (amperes, A)
Force direction on current-carrying conductors
Reverses current every half-turn for continuous rotation
Make electrical contact with rotating commutator

Perpendicular to both velocity and magnetic field
Changes direction but not speed
r=mvBqr = \frac{mv}{Bq}r=Bqmv
Smaller radius (tighter circular path)
