Tape heads


Is a tape head demagnetizer capable of demagnetizing a screwdriver? I just bought a Teak E-1 demagnetizer that buzzes when turned on but I can not get it to demagnetize a screwdriver. After performing the ritual on the screwdriver I can still feel it pull toward large metal objects.

I'm worried that it might not be demagnetizing my heads but I'm also stuck because I want to align my heads and I can not get my screwdriver demagnetized!

Thanks, Nsgarch. I am using it for a R2R. I know how to use one but I actually do have a question about the method.

First, here's what I know.
Turn the unit on about 6' away from the tape heads and approach the heads slowly. When at the heads, move the demagnetizer back and forth 4 or 5 times over the heads, guides, etc. at a speed of 1" per second. Slowly move the unit until 6' away from the tape deck, turn the demager 90 degrees, and turn off. Repeat for each head, guide, capstan, etc.

So here's my question. Do I have to move the demagnetizer 6' away from the deck after each individual component is demaged or can I just demag all of the components and THEN move the demager away from the deck?
