Will the Hollow inductor coil appear fuller? In fact, the magnetism will not be full if there is no change, because the permanent magnet data is constant in magnetism, and the soft magnetic data itself is not magnetic, so the soft magnetic data are relatively easy to magnetize and demagnetize, then when the magnetic flux reaches When the amount is measured, there may be magnetic fullness.
Hollow inductor coil magnetic saturation is a physical characteristic of magnetic data. Generally speaking, it guides magnetic data because of the physical structure constraints, so that the magnetic flux that passes through cannot be infinitely increased, so it is maintaining a certain number of conditions.
Hollow inductor coil Because the medium in the coil is air, the air reluctance is generally very large. It is difficult to make it full. Although the air-core coil is basically not full, this does not mean that the air-core coil can be used infinitely.
