natkova Posted March 1, 2014 Share Posted March 1, 2014 I have some hammer that on it self had magnetised spot. But now it don't have. Its claw hamer and it had magnetised head how to magnetise steel. Tool is something like this Quote Link to comment Share on other sites More sharing options...

metalmangeler Posted March 1, 2014 Share Posted March 1, 2014 If you take a strong magnet and rub it the same direction on the spot you want you can magnetize that spot. Quote Link to comment Share on other sites More sharing options...

Its claw hamer and it had magnetised head how to magnetise steel? Tool is something like this . Is there some way to magnetise steel easy without heating casting moulding. Without changing temperature i tihink if i rub it the magnet will fall off. Quote Link to comment Share on other sites More sharing options...

Charles R. Stevens Posted March 1, 2014 Share Posted March 1, 2014 The little bit of magnatism is ment to hold a framing nail just to get a start, and it's just in the grove. Hiring things tends to disrupt magnetism in steel. Quote Link to comment Share on other sites More sharing options...
Dodge Posted March 2, 2014 Share Posted March 2, 2014 You can magnetize a piece of steel by winding a piece of insulated wire around it in a coil and touching both ends of the wire to both terminals of a battery. I'd avoid a car battery because the result is pretty dynamic. After all you have created an electric coil and iirc, when I did it with a screwdriver and a "D" cell it of course sparked but also blew the insulation off the wire and got hot real fast. (Wear gloves) But the screwdriver did have some magnetism; at least enough to pick up and hold a screw... I'm sure a real electrician will come along and tell why it works. And maybe how to do it safely :ph34r: Scott Quote Link to comment Share on other sites More sharing options...

Pault17 Posted March 8, 2014 Share Posted March 8, 2014 Here's one for anybody. I have a piece of 3.25 round bar about three feet long that I planted in a drywall bucket full of concrete, with a rebar web a few inches from the bottom to keep the post above the bottom of the bucket. My idea was to make a beater post anvil that could be left outside. works great and it weighs about 140 lbs. The problem is that the whole thing is mildly magnetic, and I can't figure out how to unmagnetize it. works great for checking critical temp, but a bummer when everything else sticks to it, albeit mildly. sorry for hijacking, but it seemed to blend Quote Link to comment Share on other sites More sharing options...
Charles R. Stevens Posted March 8, 2014 Share Posted March 8, 2014 Good question, I know that often the local welders, building pipe fence with used oil field pipe will reort to rapping either the neggitive or positive leads around the pipe to degauss them. Hmm, might have to google degaussing... Quote Link to comment Share on other sites More sharing options...
