Question

corrected text: An electrical current-carrying conductor forms part of the rotating armature of an electric motor. It is parallel to the axis of rotation and 230 mm from it. A constant magnetic field is caused to pass over it, thus generating a tangential force, F = 16.6 N. If the armature has a moment of inertia of I = 0.14 kgm^2 and is not driving any connected load, what angular acceleration (caused by the conductor acting alone) would be?

Step 1

However, the strength of the magnetic field is not given. We need this information to calculate the angular acceleration. Without it, we cannot proceed with the problem. Show more…
