High Voltage systems, usually up to 3000V, but occasionally 5000V, are better for multipole applications or high energy magnetising systems where temperature control in the windings is important and the magnetisation pules therefore need to be as fast as possible. This magnetic field is not concentrated in a direction, so the magnetic moments are randomly spun around such that, once again, the net magnetic field is insignificant.The Bunting range of magnetisers includes the high-energy industrial BMC Series, bench-top and laboratory models, as well as magnet setters and custom-built magnetising fixtures. I cannot begin to tell you how much it has helped our operation, the magnetic filtration unit has been a real problem solver it has surpassed all our expectations. Back in the sixties in the heyday of slot racing we would take our open frame motors to a Lucas dealer who would re-magnetize them.

The rare earth magnets on the other hand, mainly Neodymium or Samarium Cobalt, require much higher fields in the range of 3 to 5Tesla. If its for open frame motors such as Hornby Dublo, Triang etc, then it will be more efficient and lower cost to replace (or supplement) the original magnets with neodymium magnets. Did try the car battery however found just connecting coils up to an old arc welder provided more magnetic strength, not even sure it's pure DC current.Owning a reasonable Hornby Dublo collection over last 50 years I am aware that some locomotives lose the magnetic strength. The steel has gone through a loop of increasing and then decreasing magnetic fields but the withdrawal step leaves a residual field, thus when you plot the field in the steel you get a loop – that’s the hysteresis loop.

Does anyone know if Ron Dodd still supplies his re-magnetiser by special request as I know they are no longer generally available?X.04s respond to the same treatment and I've fixed a couple of motor bogies by simply attaching a couple of magnets to the pole pieces.
