Question

with the help of a diagram describe how you can generate induced current in a circuit

Answer 1

exponentially approaches a value I R. If we repeat this experiment with an inductor having twice the number of turns per unit length, the time it takes for the current to reach a value of 1/2

Answer 2

1. The Axle of the coil is rotated in clockwise direction due to which the AB arm of the coil moves up and CD arm of coil moves downward direction

2. As this coil moves in clockwise direction the magnetic flux is generated between magnetic poles placed around the coil from North Pole to South Pole in between intervals

3. Due to this magnetic flux in magnetic field it induces current in the coil and the direction of the induced current is given by Fleming's right hand rule

4. In the first half of revolution the current flows through B1-AB -> BC -> CD -> B2 and in the next half of the revolution the current flows from B2 - B1

5. Therefore the direction of the induced current changes due to slip rings attached to coil ends and this type of current which changes the direction is called AC current
Hence induced current is always if AC current in nature

6. So you can induce current by magnetic field too
