Background

An inductor is a device that operates using the principle of electromagnetic induction. When current flows through a wire, a certain electromagnetic field is generated around the wire, and the wire of the electromagnetic field induces the wire in the range of the electromagnetic field. The action on the wire itself generating the electromagnetic field is called self-induction, namely, the changing current generated by the wire itself generates a changing magnetic field, and the magnetic field further influences the current in the wire; the effect on other conductors in this electromagnetic field range is called "mutual inductance". The self-inductance electromotive force in the inductance coil is always against the current change in the coil, so that the inductance coil has a blocking effect on alternating current, in addition, the inductance coil and the capacitor are connected in parallel to form a lc tuning circuit, namely, the inherent oscillation frequency f0 of the circuit is equal to the frequency f of a non-alternating current signal, the inductance and the capacitance of the loop are also equal, so that electromagnetic energy oscillates back and forth between the inductance and the capacitor, the resonance phenomenon of the lc loop is realized, the inductance and the capacitance of the circuit are equal and opposite in resonance, the inductance of the total current of the loop is minimum, the current magnitude is maximum (f is equal to the alternating current signal of 'f 0'), the lc tuning circuit has the effect of selecting frequency, an alternating current signal of a certain frequency f can be selected, and therefore, the inductance coil has the tuning and frequency selecting effects.

1. When the existing inductance coil is used, the wire self has certain resistance, so that after the current flows, the heat generated by the internal resistance of the wire is not easy to dissipate, and the use of normal equipment is influenced.

2. In addition, current coil is more mixed and disorderly when the winding, influences the pleasing to the eye of equipment, is unfavorable for the producer to sell.
