The discussion clarifies the distinction between inductors and solenoids. An inductor is primarily used to control current flow and store magnetic energy, functioning as a lossless impedance (jwL) in resonant circuits (LC) and power supply filters. In contrast, a solenoid is specifically designed to generate a magnetic field and is essentially an inductor shaped like a cylinder. Efficient inductors often incorporate ferrite or laminated steel to enhance the magnetic field (B field).
PREREQUISITESElectrical engineers, students in electronics, and professionals involved in circuit design and analysis will benefit from this discussion.
Bob S said:Inductors are generally used to control current flow as a lossless impedance (jwL), as part of a resonant circuit (LC), or as a filter or reactance in a power supply. They are also used to store energy in switching supplies. The main difference is that inductors are used to control current and store magnetic energy, and solenoids are usually designed to provide a magnetic field. Efficient inductors have ferrite or laminated steel in them to enhance the B field.
