eddy current losses

Eddy Currents - Induced currents are produced not only in the wires, but also in the block of metals. If a metallic block is placed in a continuously changing magnetic field, induced currents are set up in the body of the metallic block. In the case of the wi..

Dead Beat Galvanometer - When a steady current passes through a moving coil galvanometer, the coil undergoes a torque and does not come to equilibrium position instantly. Hence the coil is wound over a metallic frame so that the eddy currents produced in the frame can ..

In many industrial processes, the process of electrolysis is less efficient than expected from the Faraday's laws. The amount of material obtained during electrolysis is generally less than that expected due to: * Loss of energy during its flow through the system. * Some o..

In many industrial processes, the process of electrolysis is less efficient than expected from the Faraday's laws. The amount of material obtained during electrolysis is generally less than that expected due to: Loss of energy during its flow through the system. Some other side-reactions ..

Summary - If a current I flows through a potential drop V, the energy lost per second by the drifting charges is VI. In a resistor of resistance R, the loss of energy appears as heat. The rate of heat production P is P = VI = I 2 R = V 2 /R and is independent of the direction of..

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 a bar pendulum is suspended between the pole pieces of a magnet: Let us take another identical pendulum and kept in a field free region. If we oscillate both of them with the same force, it is observed that the one within the field damps faster. The 'bob' of the pendulum consists of a coppe..
