Main Question or Discussion Point
I would I go about determining the magnetic field of a bar magnet experimentally? Any ideas?
If the bar magnet is less than ~2 times longer than it is wide, you can do it this way. The equipment for this is very similar to the voltage integrator/ flip coil method I describe above and in the referenced post. The flip coil can be built using parts at the local electronics store (voltmeter, dc power supply, soldering iron, op-amp, resistor, capacitor, wire, coil form).What if I create an EMF by rotating the magnet in a solenoid and using faradays Law?
