magnetizing metal...

[myronman3]

i use this trick on tools mostly.  take a long piece of insulated wire (2-3ft) expose one-half inch of wire on both ends.    wrap the tool tightly (one layer) with the insulated wire,  then touch one end to the positive side of a car battery,  and the other end to the negative side.  be careful,  she is gonna spark.   do it 3-4 times,  and you are done.

And pray to god that battery doesn't blow up!! No offense but no thanks. If you want to do that use a lantern battery or maybe a battery charger. It would be a lot safer.    KN

Just take the 220 cord off of the dryer and hit it with that.  Use both the red and black wires on on end and the white one on the other.

Did not mean to offend anybody, I was just playing...besides, I tried that with my little brother in 1962 and he did not become magnetized.

Robert, Obviously you know very little about a/c voltages and wiring.  The red  and black wires on 220/230 vac circuits have 220/230 vac difference in potential between them. Between either the red or black wire and the white neutral wire there is 120 vac difference in potential. If you're real lucky, the circuit breaker will trip before you electrocute yourself or the wire burns up.
Even if it were possible, no permanent magnetism would take place using an a/c current since the polarity is constantly changing - the best you could hope for would be a "temporary electro-magnet" from it if you were using a soft permeable iron core.

PS: Even though you may have meant it as a "joke", there are both youngsters and immature adults who might read it and try it.  It is not very wise or intelligent to make suggestions like that on a talk forum that might cause someone SERIOUS INJURY or even DEATH. :evil:

GEEEZE this place is gettin dangerous!!!!  KN

Using DC current, you will magnitize.  Using AC, supplied from 6/12 volt transformer is a common de-magnitizer.  But why are you magnitizing in the first place??  I mean if you've got a perfectly good watch you don't need anymore, just smash it with a hammer!  Seriously, screwdrivers that are magnitized are a real pain :oh:

wow!   i thought roberts comment was funny, but slug gunner brings up a good point,  sometimes people dont realize when we are kidding.   as far as injun tricks go,  no one said you had to use them.      robert,  are you sure your brother aint magnetized? :-D

[Robert]

Dan aint magnetized.  He works in a heat-treating plant and is only attracted to aluminum cans.

:-D  :-D    :-D  :-D

Call me strange but I like to magnetize my Swiss army knife's main blade.
I normally just rub a strong magnet a crossed it several times and it works, it is not so strong that I can not open the knife but works good if I drop a small screw and it is strong enough to stick to steel shot shells. I just have to remember to keep it away from my compass

If you have a DC welder, you can use it for magna-fluxing, magnetizing or de-magnetizing. Wrap the cable carefully and it magnetizes, "Haywire" wraps de-magnetize it, and brake turnings show the cracks while it's set up for magnetizing while the current is on.  BTW, I have a brother who, while standing in water tried to put a nut back on a split-bolt connection on 220 service. He tried it when he was a kid. Didn't get magnetized, but he's still glowing!

OK,
Here's my version of a De-Magnitizer:
I took a small 6 volt transformer (one used for a GE soldering iron) and wired up to a (number?) of turns of heavy (like 10 or 12 gauge) solid copper wire house wiring and coil it around a cardboard tube of about 3-4" diameter.  Now when you plug it in and pass a screwdriver through the coil opening, back and forth, it will tend to interupt a magnetic field and clear any magnatism.  Use it to erase a recording tape.

Take an old hard drive and rip it open.  Inside you wil find some of the stongest little magnets in the world.  They are called 'rare earth' magnets.  Stroke a scrwdriver from the handle to the tip about 10 times in the same direction, and it will get a very nice charge.  You can also make a good compass by stroking a sewing needle, stick it through a cork and put it in a bowl of water.  These magnets are really usefull for a lot of things.
