Can you tell me The working of DC motor?

A DC motor works on the principle of Faraday's law of electromagnetic induction, i.e., when a current carrying conductor is placed in a magnetic field, it experiences a force applied on it.


How does a dc generator function?

The working principle is Faraday's law of electromagnetic induction. "Whenever a conductor experience the rate of change of magnetic flux an e.m.f. is induced in it",which is directly proportional to the rate of change of magnetic flux and no of conductors.

What is the difference between electromagnetic induction and magnetic induction?

Electromagnetism is first discovered by Oersted. Electromagnetic induction first found by Michael Faraday. Electromagnetism is the phenomenon in which magnetism is produced when electric current flows in a straight wire. This is the conversion of electrical energy into magnetic energy. But electromagnetic induction is the phenomenon in which electric current is produced in a wire as it cuts the magnetic lines of force. Here in the presence of magnetic energy mechanical energy gets converted into electrical energy. The former is applied in fans, motors etc. The later is utilised in generators. In an electrical bell, electromagnetism plays an important role. In case of choke, electromagnetic induction serves in a nice way. Former has Biot-Savart law, Ampere's circuital law, Lorentz force law, Fleming's left hand rule, Right hand thumb rule. The latter has Faraday's laws, Lenz law, Fleming's right hand rule.


Why is it said that generator is a motor working in reverse?

because working principle of both the things are same.The motor converts electrical energy in to mechanical via magnetic induction and generator do the exact opposite of this.And yes,you should use 'electricity generator' not only 'generator'.


How wireless chargers are working?

Inductive charging (also known as "wireless charging") uses an electromagnetic field to transfer energy between two objects. This is usually done with a charging station. Energy is sent through an inductive coupling to an electrical device, which can then use that energy to charge batteries or run the device. Induction chargers typically use an induction coil to create an alternating electromagnetic field from within a charging base station, and a second induction coil in the portable device takes power from the electromagnetic field and converts it back into electrical current to charge the battery. The two induction coils in proximity combine to form an electrical transformer. Greater distances between sender and receiver coils can be achieved when the inductive charging system uses resonant inductive coupling.
