I have a screwdriver magetiser. Magnetise when I need it, demiagnetise
when I don't. Works well on my jeweller's screwdrivers.

I find that a magnetised screwdriver usually has the wrong polarity
for the screw (or for the thing the screw is to be screwed into, if
it is metal) - and this results in the screw aligning itself at a
jaunty angle to the desired direction!

Why can't you just magnetise the screwdriver the other way around ?

First you need to have a suitable magnet about your person.

If you DO re-magnetise the screwdriver, next time you use it Sod's law
dictates that it will again be 'the wrong way round'.
