Radio amateurs often have a love-hate relationship with home-made inductors, sharing all kinds of tips and tricks as to how the most stable nanohenry inductor can be wound. But there’s another ...

Back to the basics: there are three kinds of passive electronic components: Inductors, Capacitors and Resistors. An inductor can be easily built and many types of core and bobbin kits are available.

The mutual inductor induces a di/dt proportional voltage ... This technique needs numerical calculation to obtain the current and di/dt waveforms. Another technique picks up the magnetic field and ...
