The role of induction coils in induction cookers.
Induction cooker, the use of inductive coil, inductive coil is the use of current through the coil to generate a magnetic field, when the magnetic field within the magnetic force through the bottom of the pot containing iron, that will produce numerous small eddy currents, so that the pot itself high-speed heat, and then heated in the pot of food. During use, electromagnetic waves are generated, but they are absorbed by the shielding layer at the bottom of the coil and the top plate of the iron-containing pot, so they do not leak and are not harmful to human health.
The inductor coil and the pot form a high frequency transformer, the inductor coil is the primary of the transformer, the secondary is the pot, when the inductor coil has a cross-electricity output, the induction current will certainly be generated in the pot, the induction current through the pot's own resistance to heat (so the pot itself is also a load), generating heat.
