... wherein four drive motors actuate pairs of orthogonal rollers pressing against the ball to create motion in the plane, while a fifth drive motor provides yaw motion to affect the body azimuth. Second, there is the “tri-wheel” principle [3] wherein three motors drive the ball in all three DOFs using ...
Electromagnetism
... As the magnet is moved past the coils, an induced current in the coils (generator effect) will generate a magnetic field to oppose the motion of the magnet The right end of the coil will become a north pole to exert Fm to the right onto the magnet moved left. When the magnet is pulled out to the rig ...
