Recently I posted a tutorial involving unscrewing panels and opening parts of a laptop. Small and easily misplace-able screws are involved there which my roll into crevices and corners becoming difficult to remove especially if it falls inside the laptop itself (big problem!!).
So I strictly instructed to use a magnetic screw driver to handle those screws easily.
But what if you dont want to spend on a costly magnetic screw driver and want to use the normal one you have? Then we can magnetize it!
Tools:
1) Bar magnet(preferably).
2) Screw driver to magnetize.
Procedure:
The procedure is a 10th grade Science lesson on how to give magnetic properties to non-magnetic metal objects using Magnetic Induction.
Step 1:
Run any pole of the magnet along the portion of screw driver you want to magnetize in single direction only.
Step 2:
To come back to the start point don't directly follow a horizontal path backwards. Take the magnet well above the screw driver and come back in a parabolic path.
Do this a few hundred times (200 gives pretty strong magnetization). Do more for a stronger magnetization.
It will not magnetize if you keep running the magnet back and forth.

How long does this INDUCED MAGNETISM stay? Does it retain it's intensity forever? Or do we need to repeat the procedure if we are using the screw driver after a considerable gap, say 4-5 months?
ReplyDeleteIt loses its intensity over time, yes...but then again there are 2 cases.
Delete1) If you are using the object frequently (striking here and there at times) then the array of polarized particles gets disturbed.
2) It will be lost very less in case you keep it still for 4-5 months. So much less that you wont feel it unless you test with some considerably heavy metal object that you could lift when you magnetized..but after 4 months you can't lift the same object.
