We may not understand what is the inductance coil, the coil of the members is too large. Come to know about it today. Inductive coil is the electromagnetic induction device which is made of insulated wire. It is one of the common components in the electronic circuit. When there is current in the coil, the magnetic field is generated around the coil. What is mutual inductance? When it is close to each other, the magnetic field of an inductance coil will affect the magnetic field of the other two. Speaking of the coil, many customers want to inductance amount can be as large as possible, actually inductance is more big, the distributed capacitance of the coil inductance. So we will go to a number of manufacturers to explain some of the new customers in this regard.
