I need to magnetize a screwdriver, can anyone tell me how?
Thanks
I built a Mag/Demag Device by assembling a core, about 1" in dia., of 16p
nails with the heads, and points cut off. I constructed a form, and wound a
coil around the nails. A double throw switch allowed the coil to be fed with
AC, or DC via a bridge rectifier, and a momentary contact switch to operate.
A fuse, and a case for safety completed the unit.
Holding the ferrous metal implement very close to the core end, and
operating the unit in the DC mode allowed for magnetization. Placing
magnetized metal close to the core end, and turning on the coil in the AC
mode while moving the magnetized metal slowly away while rotating the
magnetized metal in a circular motion, a few feet away before turning off
the coil, will do a good job of demagnetizing.
