![]() I will not recommend any specific model or manufacturer, but if (audio)transformers is your thing, it might be worth investigating further. There are some (relatively) cheap network analyzers available for low frequency testing. V = - N \cdot \frac)įor audio application you should probably consider to use \(-1dB\) as the design criteria however. ![]() ![]() Hence it can be reasoned, that as long as each coil is exposed to the same magnetic flux change, the total induced voltage is given by: The voltage induced in a coil is given by Faraday's law of induction as: This can be understood by realizing that all the turns of the windings around a iron core are exposed to the same magnetic flux. It is well known amongst most electrical engineers that the voltage(and current) transformation ratio equals the turns ratio. In order to improve this coupling, it is common for the windings to reside on a core of low reluctance material. Transformers consists of two or more windings that are magnetically coupled towards each other.
