(The forces add because they are in the same direction.) The force on an individual charge moving at the drift velocity vd is given by F=qvdBsinθ.
The magnetic force on current-carrying conductors is given by F=πBsinθ, where is the current, l is the length of a straight conductor in a uniform magnetic field B, and \...The magnetic force on current-carrying conductors is given by F=πBsinθ, where is the current, l is the length of a straight conductor in a uniform magnetic field B, and θ is the angle between I and B. The force follows RHR-1 with the thumb in the direction of I.\
