This unit (IPC-4924-W) is ideal for demonstrating the effects of electromagnetics, simply place a suitable pick-up coil directly connected to an oscilloscope into the Field Coil Loop and observe the resulting waveform displayed. The unit simply requires an AC voltage supply of approximately 2V AC (see instructions for full supply details) via the two front 4mm sockets.
An ideal power supply for the AC Magnetic Field Coil is our Multitap Transformer power supply (IPC-0484-P) which provides a 2V AC output suitable for this application (again see instructions for full supply details).
