Tool Inexpensive demagnetizers?

Do you just stick the screwdriver in and hit the switch?

Turn the switch on, insert the screwdriver, hold onto it for dear life because all it wants to do is head over the side, then pull it out slowly.
The metal filings stick to side walls and when you turn the switch off you can empty them out.

Would probably just magnetize them. Could you imagine magnetized squirrels running around? Family Cat sticking to the fridge lol.
