what is induction cooking

Magnetic Induction - If you hold a bar magnet near or in contact with a soft iron nail as shown in figure, the nail becomes a magnet by induction. The nail retains its magnetism only as long as the magnet is held near it or in contact with it. It will even pick up several other ..

Induction furnace separates certain metals from their ores. It is done by heating the metal. The type of heating done is called induction heating. This heating can be done using eddy currents. The metal to be heated is placed in a high frequency changing magnetic field. Strong ..

If you hold a bar magnet near or in contact with a soft iron nail as shown in figure, the nail becomes a magnet by induction. The nail retains its magnetism only as long as the magnet is held near it or in contact with it. It will even pick up several other nails. But is loses its magneti..

The word 'Induction' means method of reasoning from individual cases to general ones or from observed instances to unobserved ones. Many important mathematical formulae are such that a result is formed by some means which does not provide for a direct proof. Mathematical Induct..

Mutual Inductance - We know that if a current builds up or varies in a coil, the flux change leads to induced e.m.f in the same coil. This can happen event mutually between two interacting coils are close together, and if current is passed in one of them, it sets up a magnetic flux surrou..

We know that if a current builds up or varies in a coil, the flux change leads to induced e.m.f in the same coil. This can happen event mutually between two interacting coils are close together, and if current is passed in one of them, it sets up a magnetic flux surrounding itself. When the second ..

Michael Faraday the English scientist was the first person to prove that a magnet can create a current To test this he moved a magnet towards and away from the coil of wire connected to a galvanometer He observed that there was a deflection in the galvanometer indicating that a current is i..

Charging by Induction - In the previous section we saw how a body is charged by friction . Let us now see how we can charge a metallic sphere by induction. Fig (a) shows an uncharged metallic sphere supported on an insulating rod. A charged plastic rod is brought close to the sp..

Faraday and Henry performed lots of experiments to learn about the connection between electricity and magnetism. The results of these experiments have led to the life styles of todays men, who made life easy by using lots of electrical applications. Some of the experiments are as follo..
