Can somebody point out the difference between these coils? Because to me they seem to do the same thing.
The reverse wound bifilar coil is wound in such a way that in any one position on the coil the current is flowing both ways which results in a zero net magnetic field.
Bucking coils consist of two coils. One wound CW and the other CCW. The coils are positioned end to end in a magnetic poles opposing configuration ie. NN or SS. This also results in a zero net magnetic field.
