Question

1. A simple electric motor is made when a coil or any closed loop of conductor moves through magnetic field lines. 2. In a generator, the input is electrical power and output is mechanical power. 3. Faraday's law says that a changing magnetic field produces an electric field 4. A simple DC motor can be assembled using a single coil that rotates in a magnetic field. 5. Rotation of a coil in a magnetic field produces an emt. 6. A simple electric generator is made when a coil or any dosed loop of conductor moves throu magnetic field lines, 7. The transformer is an example of dynamic electrical machine. 8. In a generator, the input is mechanical power and the output is electrical power. 9. Motor and generator are both static electrical machines. 10. The working principle of DC generators is based on Faraday's law of electromagnetic induction

Answer 1

Answer:

The apparatus used by Faraday to demonstrate that magnetic fields can create currents is illustrated in the following figure. When the switch is closed, a magnetic field is produced in the coil on the top part of the iron ring and transmitted (or guided) to the coil on the bottom part of the ring. The galvanometer is used to detect any current induced in a separate coil on the bottom.
