Measuring the induction voltage in a conductor loop for a variable magnetic field - with Power-CASSY as variable source of current

In the experiment P3.4.3.2, induction coils with different areas and numbers of turns are arranged in a cylindrical field coil through which alternating currents of various frequencies, amplitudes and signal forms flow. In the field coil, the currents generate the magnetic field

and I(t) is the time-dependent current level, N₂ the number of turns and L₂ the overall length of the coil. The curve over time U(t) of the voltages induced in the induction coils is recorded using the CASSY system. This experiment explores how the voltage is dependent on the area and the number of turns of the induction coils, as well as on the frequency, amplitude and signal form of the exciter current.
