I need to make a circuit to power an overunity generater
Here are a couple of links that give good examples of how to manufacture a gauss-probe.http://www.coolmagnetman.com/magmeter.htmwww.physics.armstrong.edu/projects/magnetometer.html

There are a couple of tricks for detecting magnetic field. The two I have seen most often are pick-up coils, and Hall effect sensors. A pick-up coil gives you voltage proportional to the time-rate change of the magnetic flux through the coil, and proportional to the number of turns, and this is just Faraday's law of induction.http://en.wikipedia.org/wiki/Faraday%27s_law_of_induction#Flux_through_a_surface_and_EMF_around_a_loop Note this kind of sensor requires a magnetic field that is changing, and gives a response proportional to this time-rate of change. If you want a sensor that responds to magnetic field directly, and that will also work with DC magnetic fields, then you want a Hall effect Sensor.http://en.wikipedia.org/wiki/Hall_effect_sensor There are a couple of different kinds of Hall effect sensor. If you want a response that's proportional to magnetic field strength, then they call this kind a linear hall effect sensor. There are other kinds of Hall effect sensor that just sort of switch on (or off) depending on the magnitude of the field they're detecting. These switchy kind of Hall effect sensors get used a lot in position sensors in brushless motors; i.e. a magnet moves by the sensor, and then the sensor switches, and this tells the controller the position of the rotor.
Several loops of wire, connected through a resistor, will sense a magnetic field.Basically, it's using a solenoid in reverse, and it's the basis for metal detectors, among other uses (like current sensors...)As a sensor, fine gauge wire can be used to increase the sensitivity with minimal size. The larger in diameter you make the loop(s), the more sensitive it will be. The more loops you use the more sensitive it will be.
(measure the voltage across the resistor to detect the field).It can get more complex depending on what you want to do, (for instance, in commercial metal detectors, the system is active rather than passive as in my example and more complicated than I care to outline right now) but that's the basics.
Far too vague. Have you tried praying or sacrifices? L
You could do just about anything you want for your "overunity generater" [sic]. Just make sure you include a carefully hidden battery so people will believe it actually works.
