About 20 volts AC is sufficient to generate a sufficiently strong alternating magnetic field, at this voltage the coil will take about 2 - 2.5 amps. An AC plug pack of appropriate rating is required. De-magnetising works by applying an alternating magnetic field stronger than the residual magnetism you are trying to remove, and then reducing the applied field to zero. If you have a Variac then the field can be reduced easily. If you dont have a Variac, apply the AC to the coil, hold it near to the monitor, and move the coil away until the screen picture doesnt wobble any more. Dont be too alarmed by the screen going haywire when the coil is near to it. Gauss...Johann Carl Friedrich Gauss, 1777-1855, brilliant mathematician and scientist.

There will be an unknown stray field outside the motor, due to the motor not being ideal, and fields from the cables,but that could be anybodies guess.	Guest (0)
