Can anyone tell me the value of the resistor, the one in mine is 200k ohms, I'm thinking of changing it to reduce the magnetic pull, it seems too strong for something delicate like a watch.
I recently bought one of these do demag a watch hairspring (Still in the watch!), I pressed the red button and the locknut wasn't screwed on, The button went inside and the LED indicator also went in, I contacted the seller and told him what happened and he replied 'Can you use it some more'!, I told him no because the whole lot had gone inside!
I tried holding the red plastic switch first off to screw the nut on but it seemed lioke the threads were bad as that's when it went fully inside!, I opened the box up and pushed the switch through from the inside then replaced the nut whilst pushing down with pliars (And put the LED in first) and it's all working now!! 👍
I would like to have something like this as both a magnetizer and a demagnetizer. I would magnetize some screwdrivers that need to be magnetized, I have a few of those. still can't justify the price even though it's probably not that much.
I bought a degausser many years ago(late 70's) to degauss my tape recorder heads. Even though it came with basic instructions I never could work out how or if it really worked or caused damage to the machine. Still have it. I'll try to demagnetize a screwdriver.
I'm just imagining what you could achieve with a microwave oven transformer with its secondary removed, and with the yoke opened up at one end [to form an 'E' core]. The magnetic flux would be immense!
Thanks Clive I just bought one of these things and now I've seen this I am happy. Even though I had to repair the screw post which had snapped off as I couldn't be bothered to send the thing back
A running a/c fan motor will do it. Even a small one like a computer fan can demagnetize a watch for example.
Yes, there still pretty cheap.
Just used mine on two watches a few minutes ago.😎👍

Am learning so much today! Thanks!
I do wish these would be battery powered. Mains voltage with a cheap switch and no fuse isn't very comforting.
Another concise video, containing everything I needed to know. Thank you Clive

Actually, it's not about the price of the tool, it's about the knowledge of the user !
Thank you for teaching a good lesson.

I wonder if you could use one of those big clunky wall adapters to degauss something
When degaussing tape heads, you would get the degausser, touch the tape head and move it away in a spiral motion.

Thank you
Is there any way to remagnetize it quickly other than heating it up and sticking a magnet on it?
