Which two laws are used to find the direction of eddy currents?
Write the applications of eddy current. Answer in brief.
Eddy current induced in the rails oppose the motion of the train.
Electromagnetic damping is inversely proportional to
Electromagnetic damping is similar to
Electromagnetic damping is associated with:
Why are the core of induction coils constructed as a number of thin strips instead of a solid block?
Which of the following is a disadvantage of eddy currents?
The working of an analogue type electric power meter is based on
Which of the following is responsible for the working of an analogue electric power meter?
Which of the following is essential for the working of an induction furnace?
On what principle does an induction furnace works?
Which of the following does not use the application of eddy current?
Assertion: A thin aluminium disc, spinning freely about a central pivot, is quickly brought to rest when placed between the poles of a strong U-shaped magnet.
Reason: A current induced in a disc rotating in a magnetic field produces a force which tends to oppose the motion of the disc
