What change do we observe in the galvanometer if the current in the solenoid coil is increased?

What change do we observe in the Galvanometer when the current in the Solenoid coil is switched off?

What change do we observe in the galvanometer if the displacement of the solenoid is faster?

What change do we observe in the Galvanometer when a current is passing through the soleoid coil and the coil is displaced laterally with respect to the coil?

What are the changes observed in the later period of adoloescence?

What are the types of moving coil Galvanometer?

What do you observe in the following Pictures?:

Answer the following questions : Observe the following figure. If the current in the coil A is changed, will some current be induced in the coil B ? Explain.

A solenoid is connected to a battery so that a steady current flows through it. If an iron core is inserted into the solenoid, will the current increase or decrease?Explain.

A long solenoid ‘S’ has ‘n’ turns per meter, with diameter ‘a’. At the centre of this coil we place a smaller coil of ‘N’ turns and diameter ‘b’ (where b < a). If the current in the solenoid increases linearly, with time, what is the induced emf appearing in the smaller coil. Plot graph showing nature of variation in emf, if current varies as a function of mt^2 + C .
