I'm following Birk Peterson's published plans (Machinist's Workshop April/May 2003) to build a magnetizer/demagnetizer using the coil from a surplus solenoid. On first pass it worked real well but after two or three 2 second cycles it burned up the coil. The coil came from a big Dormeyer intermittent duty relay. If I use a coil from a continuous duty relay will it survive longer?
It's a 115 Vdc circuit with a bridge rectifier to energize dc to mag and A/C to demag.
Thanks in advance.
