"WebThe magnetic force on a current-carrying wire in a magnetic field is given by F → = I l → × B →. For part a, since the current and magnetic field are perpendicular in this problem, we can simplify the formula to give us the magnitude and find the direction through the RHR-1. The angle θ is 90 degrees, which means sin θ = 1. " - Field current if

A family of inverted V curves of a synchronous motor obtained by plotting the power factor versus field current is shown in Figure-2. The peak point on each of these curves indicates unity power factor.
