Ron Kita, Chiralex Few people realize that when one spins a symmetical magnet
as a ring magnet-the flux lines remain stationary in space. This is the
principle of the One Piece Farady Homopolar Generator.
I am not so sure. Think that this works because the magnet is constantly
accelerated. We tend to make circular motion more mysterious than it really
is.If we picture a representative part of the magnet traveling clockwise around
a clock face then:
At 12, it has just stopped decelerating in the upward direction, it is just
starting to accelerate in the downward direction, is at full speed traveling
toright but is decelerating its rightward direction.
This constant acceleration in one direction and simultaneous deceleration in a
direction that is perpendicular to that, is taking place at every point around
the circle, It is taking place constantly at every location throughout the
rotating magnet.
In other words, every part of the magnetic field itself is always accelerating.
As with alternating current being out of phase with the driving voltage, it is
the changein the magnetic field that is inducing the current. In this case,
the change is constant and also is the current constant.
