Question

(2) Observe the following diagram and write the answers of the given sub-

questions:

a. Which instrument the above figure shows?

b. Which rule is used to determine the direction of the current produced?

c. State the rule.

d. In which direction (B1 to B2 or B2 to B1) will the current flow in the

external circuit in that situation?

e. What change will have to be made in the coil for increasing the

current several times without changing the magnet?​

Answer 1

Answer:

a) The above figure shows the figure of generator .

b) Fleming's right-hand rule shows the direction of induced current when a conductor attached to a circuit moves in a magnetic field. It can be used to determine the direction of current in a generator's windings.

c) Fleming's right-hand rule gives which direction the current flows. The right hand is held with the thumb, index finger and middle finger mutually perpendicular to each other (at right angles), as shown in the diagram. The thumb is pointed in the direction of the motion of the conductor relative to the magnetic field.

d) Current flows from B2 to B1 in the external circuit.

e) If distance is reduced then current would increase.
