I want to magnetize screw bits for my screwdriver.
From what I gather I need to attach a "insulated" wire to a battery,
and wrap the wire around the metal.
What strength of battery should be used? A, AA, D?
For how long should I magnetize the metal to have it magnetized for a
good while?
How do I know if my bits contain the types of metals to keep the
magnetization (not a soft iron, whatever that means)?
