A flexible wire of irregular shape, abcd, as shown in the figure, turns into a circular shape w,hen placed in a region of magnetic field which is directed normal to the plane of the loop away from the reader. Predict the direction of the induced current in the wire.
While sitting a lawn, Ashok and his friends saw that a bird was sitting on high voltage wire. They observed that when a current passed through the wire, the bird sitting on it flew away. People along with both of them gave their opinions and reasons for it, but nobody was able to give a proper balanced option, but in the last Ashok explained the reason behind it. (a) What are the value displayed by Ashok ?(b) Why as soon as the current passed through a high voltage wire, the bird sitting on it flew away ?
The electric current flowing in a wire in the direction from B to A is decreasing. Find out the direction of the induced current in the metallic loop kept above the wire as shown.
Isabella used an induction stove and explains to her neighbour that due to shortage of LPG one must utilize other sources that are available to produce heat energy; being a Physics teacher Isabella, explains that the oil companies are trying their best to meet the demands for LPG and that as a good citizen one must use other sources wherever feasible. Isabella uses an induction stove having a value of 7 H inductor and the flow of current from 10 A to 7 A in x 10-2 seconds. (i) In the above, what is the quality, you find in the Physics teacher ?(ii) Calculate the emf generated in the above ?
