The hollow core of the present invention includes a hollow core for increasing the induced current, and the cross section of the hollow core may be non-solid and have various shapes, and in the illustration of the present embodiment, fig. 1, the cross section of the hollow core is annular. The hollow core is not limited to the straight cylindrical shape shown in fig. 1, and the hollow core may have various shapes as a solid core.

Specifically, a first lead (1) with an insulating layer is wound on the outer surface of the hollow iron core, and the first lead (1) is connected with a power supply; winding a second wire (2) with an insulating layer on the outer surface of the hollow iron core, wherein the second wire (2) is connected with an electric appliance or an instrument, and the second wire (2) is connected with the electric appliance and the instrument at the same time; when there is a change in current in the first conductor (1) loop, there is an induced current in the second conductor (2) loop.

For example one, i made the following application experiment: as shown in fig. 2, the section of the hollow iron core is a circular ring, the outer diameter of the circular ring is 9.1 cm, the inner diameter of the circular ring is 7 cm, the length of the iron core is 4.35 cm, a first lead (1) with an insulating layer is tightly wound on the outer surface of the hollow iron core for 3 circles, and the first lead (1) is connected with a power supply and a 40W bulb; tightly winding a second lead (2) with an insulating layer on the outer surface of the hollow iron core for 3 circles, wherein the second lead (2) is connected with a universal meter; when the first lead (1) loop is connected with 220V alternating current of a power supply, the universal meter connected with the second lead (2) displays that the induced current is 0.023 mA;

a solid iron core which is made of the same material as a hollow iron core, has the same length of 4.35 cm and the same diameter of 9.1 cm is adopted, the winding of a first lead (1) and a second lead (2) on the solid iron core is completely the same as the winding on the outer surface of the hollow iron core, the connection of the first lead (1) with a power supply after winding on the solid iron core and the circuit formed when a 40W bulb is wound on the hollow iron core are completely the same as the circuit formed when the hollow iron core is wound, the connection of a universal meter after winding on the solid iron core and the circuit formed when the hollow iron core is wound on the second lead (2) are completely the same, and when the first lead (1) circuit is connected with 220V alternating current of the power supply, experiments show that the universal meter connected with the second lead (2) displays that the induced current is also 0.023 mA.
