There are two basic types of magnetic flux measuring devices. For larger
magnetic field (i.e. >10 gauss) a hall effect meter is used. For Low level
magnetic field a magnetometer is used. Magnetometers come in two types. One
is a fluxgate magnetometer which you can buy the sensor
From: "Jack M. Janicke" <magres@webspan.net>
Organization: Magnetic Research,Inc.

The other is a neutron magnetometer. The single axis fluxgate magnetometer
is easiest and plans are availabe form Magnetic Research and Jack's prices
are the most reasonable I have found anywhere.

If you are measuring magnets you would want the hall effect type and
sensors are available from many electronics supply houses. All you would
need is an power supply and amplifier for one of these.
