The magnet coil

2016-08-19 00:51

The magnet can be induction to the space of all magnetic signals around within a certain range, continuous in each frequency resonance is generated at the top of the coil and variable capacitance and resonant frequency of the corresponding foreign frequency will be selected and amplifier with sound, deviate from the bar on the resonant frequency of the signal will be coil or filter capacitance decays away be being the.
Inductance: when the coil through the current, the coil in the coil to form a magnetic induction, the induction magnetic field will produce the induction current to resist the current through the coil. The interaction between the current and the coil called for the inductive reactance of the power, also is the inductance, the unit is "Henry" (H).

Inductance coil is a circle by a circle around the insulating tube, the wires are insulated from each other, and the insulating tube can be hollow, but also can contain iron core or magnetic powder core, referred to as the inductance. With L said that the unit has Henry (H), Henry (mH), Wahenry (uH), 1H=10^3mH=10^6uH.
The magnet inductor to point:
1 low cost general inductors.
2 using ferrite core.
3 high saturation current.
4 coil bulk dip (varnish), pin tin.
5 lead-free environmental protection
Rod inductor type:
R3*12 R3*15 R4*15 R4*20 R3*10 R5*15 R5*20 R5*25 R5*30 R6*10 R6*15 R6*20 R6*25 R6*30
