What happens to a coil when AC current is passed through it? How does it avoid getting burnt?
When an alternating current passes through a coil, the following situations occur:I. Electromagnetic effects1. Generation of a magnetic fieldWhen an alternating current passes through a coil, an alternating magnetic field is generated around the coil. The intensity of this magnetic field changes with the change of current.For example, in an electromagnet, when an alternating current passes through a coil, a magnetic field that attracts ferromagnetic objects is generated. The direction and intens
