The working principle of self - adhesive coils

Self-adhesive coils is very big help to us in our daily life, because a lot ofthings have to use self-adhesive coils, now the technology is so advanced,many things are advanced, but also convenient and simple many, thus improving people's living standard, but it is good will harm.

Inductance is uses the principle of electromagnetic induction to work. Hollowself-adhesive coils when current flows through a wire coil will produceelectromagnetic fields when the self-adhesive, self-adhesive coils certainaround this wire, and the wire of the electromagnetic field itself in theelectromagnetic field within the scope of the attack. The hollow coil wireinduction effect of hollow self-adhesive coil wire generates an electromagnetic field's own attack effect, called the 'self', namely the conductor current changeproduced by the magnetic field change their hollow coil, the magnetic field is further affected the electric current in a wire; in other wires which producesaudio coil of an electromagnetic field scope effect, called 'Transformers'.

The inductance coil of the electrical characteristics and capacitor instead,'resistance high frequency, low pass. That is to say, the high frequency signalthrough the inductance coil will encounter great resistance, it is difficult topass; and on the present low frequency signal after it is the resistance is small,i.e., low frequency signal can be easily through it. The inductance coil DCresistance to almost zero. The audio coil resistance, capacitance and inductance, they to stream audio coil signal circuit dynamic will present some resistance, the resistance we call for the 'use' inductance coil impedance impedance presented to the current signal is self inductance coil coil.Sometimes we call it 'the inductance' or 'coil', represented by the letter'L'. The winding inductance coil, the number of coils wound we called it the coil turn number''. The above is the effect principle of hollow coil, as Dongguan hollowcoil in the market has its independent status and advantage.
