HOW IS MADE OR PDF ..... I THING MAGNETMETER IS COLECTING PERMANENT MAGNET FORCE TO ITSELF AND IS AMPLIFAED
ITHING Steven Mark IS DOING THIS WHIT 2 PERMANENT MAGNET IS BRING TO THE HIS TPU TO AMPLIFAED VOLTAGE IN THE TPU AND THEN HI START TO ASCILATIONS
MY TEORY <<<<< IF YOU HAVE ORDENERY LOUD SPEAKER AND HIS COIL PUT PUSLE SMAL ELEK.ENERGY THEN YOU PUT IN TO A FIRST IN SMALL MGNET THE MOVMENT WHIL BR SMALL ,,, THEN THE SAME COIL WHIT SAME PULSE SMAL ELEK.ENERG. PUT IN TO A VERY BIG PERM. MAGNET THEN THE MOUVMENT WHIL BE BIGER >>>>>> CONCLUTIONS FOR THIS YOU CAN CREATED POWER WHIT SMAL ELEK. ENER WHIT BIG MAGNET YOU CREATE THE ELEKTRONS IN THIS WIRE TO BE AMPLIFAED IF YOU BRING BIGER AND BIGER MAGNET YOU HAVE MORE AMPLI ELEKRONS ... PLEASE REPLY
CD. here's fluxgate magnetometer. (https://overunityarchives.com/proxy.php?request=http%3A%2F%2Fbeale.best.vwh.net%2Fmeasure%2Ffluxgate%2Fsensor.jpg&hash=f5c0cd0ca9c4efd6225b74cb15b8d9dffd19b142)
However, this is not the only way to build one. Do a google search for fluxgate magnetometer, and then click, images, from there. You will get lots of pictures of different magnetometers.

and dont forget the "demodulator"
