Hello again everyone,
I'm in the process of winding/sourcing out coils to produce induced flux of one or the other pole orientation. I understand that when a coil is induced by a permanent magnet the resulting force will be opposite and equal to the force that caused it. So if one induces the coil with the positive end of the magnet it will induce a positive field and vise versa. But, does the direction of the coil winding in a single closed loop coil, let's say clockwise, result in a positive pole or a negative pole, or is it the current flow that would determine pole designation? I know that when a cylindrical coil is induced by the positive side of a permanent magnet, the opposite end of the coil will automatically be the opposite. But what is not clear is, in the case of levitating trains (Inductrac) a figure of eight coil is used to keep the vehicle centered on the track. If I understand this correctly the first part of the loop is induced, by the passing train, which results in an opposite pole in the second part of the figure of eight loop. So, the current is traveling in a clockwise direction in the first part of the loop and counterclockwise in the second part of the loop, giving way to opposite poles produced from the initial pass. Am I looking at two separate issues here?
Thanks everyone
