An electric field is induced by any region of space in which
(a) a magnetic field’s orientation is at right angles to the electric filed.
(b) the accompanying electric filed undergoes change in time.
(c) a magnetic field changes with time.
(d) All of these.
The correct option for the statement “An electric field is induced in any region of space in which.”
Answer to Problem 9RAT
The correct option for the statement “An electric field is induced in any region of space in which” is option (c).
Explanation of Solution
According to the Law given by Faraday, a voltage induced in a closed coil loop or circuit varies linearly with the number of loops and the change in the magnetic field. This also gives rise to the change in the electric field of the circuit. So, the variation in the electric field associated with the circuit changes with the rate at which the magnetic field changes.
The direction of the electric field induced is perpendicular to the varying magnetic field. Thus, an electric field gets induced in the region of space in which a magnetic field gets vary with respect to time.
Conclusion:
Therefore, the correct option for the statement “An electric field is induced in any region of space in which” is option (c).
