Detailed explanation-1: -If a coil of wire is placed in a changing magnetic field, a current will be induced in the wire. This current flows because something is producing an electric field that forces the charges around the wire.
Detailed explanation-2: -When an electric current flows through a wire, the wire gets heated ( heating effect of current) and a magnetic field is produced around it ( magnetic effect of current).
Detailed explanation-3: -Energy Transformation – Energy can be transformed from one form to another. When a wire with a current is placed in a magnetic field, electrical energy is transformed into mechanical energy. The transformation happens when the magnetic field produced by the current causes the wire to move.
Detailed explanation-4: -Motors consist of loops of wire in a magnetic field. When current is passed through the loops, the magnetic field exerts a torque on the loops, which rotates a shaft. Electrical energy is converted to mechanical work in the process.
