I made a coil form with a piece of 1" PVC pipe 1" long with piece of
plexaglass on each end. The plexaglass is just to hold the wire in
place until the polyurethane varnish dries. I wound #24 enamel
coated copper wire onto the coil form and coated it with urethan as I
went. I wound it until the coil was about 2 1/4" diameter. Not sure
how many turns are on the coil. In a few days the urethane was dry
and I removed the coil form. The finished coil is 1.25" ID by 2.25"
OD by 1" long. I have 2 capacitors in parallel 7400 MFD 200 VDC
each. I have a bridge rectifier to charge the capacitor with a serge
current limiting resistor. I plug it into the wall outlet 120 volts
AC it charges the caps to about 170 volts throught the serge
resistor. I have a push button switch between the capacitors and the
coil. The switch needs to be able to handle the discharge current
from the 2 caps. I built a homemade switch sorta like a morse code
key. I charge the caps then discharge them into the coil. A magnet
will soak up the magnet field for only a few seconds and it has a
half life of about 2 seconds. There is a limit to how much magnet
field a magnet will take. I have no way to measure the exact magnet
field or strength of a magnet all I can say is how much weight a
magnet will actually pick up and about how long the magnet will hold
the magnet charge. I would assume different magnet materials will
that a differet charge.
Be sure to place the magnet in the coil correctly. This device will
also reverse the magnet field of a magnet. If the magnet is setting
in the coil at a 45 deg angle the magnet field ends up being at 45
deg angle in the magnet. This is how the manufactures that make
magnets charge a magnet. When the metal is formed into a magnet
shape it has not magnet field until it is charged.
I have been trying to think up some experements to do with a Tesla
Coil using magnets. About all I can do is experement and see what happens.
