Re: are these magnets a good buy

Hello,
are there any guidelines for choosing magnets, size, shape and strength in
relation to the output power of the generator.
How do Ceramic compare with Neomydium?
Are there any good magnet suppliers in UK or Europe. Magnet4less have good
prices and range, but shipping charges to Europe are very high.
TiA,
Mike.

a address for some epoxy coated magnets. the price seems very reasonable. but
they are n35 grade yet have a pulling force of 70 pounds. any opinion would be
helpful thanks.

Pulling force is related to size. Induced voltage in a wire is # of lines cut per unit time, thus velocity and flux density. The higher the magnet number the...	Kirk McLoren kirkmcloren	Jun 21, 2009 5:15 pm

Your flux will increase with thickness, so stacking magnets will increase the force. Some incidental losses may occur, they they will be very minor. Intermag...	offlogic	Jul 8, 2009 12:49 pm
