Explanation:
Detailed explanation-1: -Inside the guts of a microwave, a device called a magnetron channels electrical energy from a power outlet to a heated filament, creating a flow of electrons that in turn transmits microwaves into the cooking chamber through an antenna.
Detailed explanation-2: -The magnetron takes electricity from the power outlet and converts it into high-powered microwaves when pressed start. The magnetron sends these waves into the food compartment through a channel called a waveguide. The food sits on a rotating table, spinning slowly around, so the microwaves cook it evenly.
