According to Faraday's law of electromagnetic induction, an electromotive force (emf) is induced in a conducting coil by a time-varying magnetic flux through the coil. This can be written ... , where the magnetic flux through the coil is given by ... . For a circular search coil of radius ... wound with ... turns of wire, ... , where ... is the angle of the coil to the magnetic induction ... , which is assumed uniform over its cross section, although variable over time. The function generator varies the voltage through the Helmholtz coils, which produces a time-dependent magnetic induction ... mirroring the signal profile. Both the function generator and oscilloscope show stroboscopic plots of voltage versus time. The dual-trace oscilloscope can show both signals simultaneously, and we have taken the liberty of coloring the search-coil signal red.
