DC1390R-154K Working Principle

At the most basic level, a fixed inductor is a coil of wire with a core at its center. The inductor works according to Faraday\'s law of induction and relies on the relationship between an electromagnetic field and a changing current. When current passes through the inductor’s coils, it creates a magnetic field that induces a voltage in the coil. This induced voltage has a polarity that opposes the changing current, thus limiting its flow.
