[net.physics] Create a Permanent Magnet?

joe@zinfandel.UUCP (04/03/85)

	I want to strongly magnetize the dip-sticks and all three
oil drainage plugs in my new car so that they attract and hold as
much of the ferrous particulates as possible during the break-in
period.
	Does anyone out there know of a clever way to do this?

Thanks,

	Some time ago I was helping a friend of mine fix his tape
recorder when, as predicted by Murphy's law, a little screw fell
into the machinery, in a position that was virtually unreachable.
What I needed was a magnetized screwdriver, but my friend didn't
have one. So I took a regular screwdriver, I found some thermostat
wire and wrapped a couple hundred loops of wire around the shaft
of the screwdriver. Then I went outside to my parked car, opened
the hood and connected the wire across the battery terminals, while
holding the coil in my hand. It took less than a second for the
wire to become so hot that I had to disconnect it from the battery,
but that was quite enough to magnetize the screwdriver.

	If you use bigger wire you will be taking fuller advantage
of the battery's powerful discharge capability. This means that
you won't need as many turns for full magnetization; However, if
the wire is very big you should watch out for the spark, it's
probably a good idea to wear safety glasses. Also, it takes a
fraction of a second to magnetize the material, so there's no need
to keep the wire connected for any significant length of time;
make sure it does not overheat and burn the insulation.

	I presume that your engine block is not made of aluminum.

Alternately, Radio Shack sells ferrite magnets for 10 cents a
piece and with a little super glue and a new oil filter you can
mount these magnets where they will trap these particles in 
a location which is benign and where there is a high volume flow.

Putting them on the "dryer" unit in your airconditioner is also
a good idea.  The super glue will hold them in place and putting
a drop in the intended spot and quickly wiping it away with a
clean paper towel will insure a better bond on an otherwise oily surface.
