(a) current.
(b) voltage.
(c) electric field.
(d) All of these.
The correct option for the statement "If you change the magnetic field in a closed loop of wire, you induced in the loop a(n)".
Answer to Problem 6RAT
The correct option for the statement "If you change the magnetic field in a closed loop of wire, you induced in the loop a(n)" is option (d).
Explanation of Solution
According to Faraday's law, the amount of induced voltage in the closed-circuit varies linearly with the rate at which the magnetic field associated with the circuit changes. When a person changes the magnetic field in a closed loop of wire, a voltage is induced. Moreover, as the induced voltage increases in a closed circuit, the magnitude of the induced current also increases.
The law also suggests that when the magnetic field in a closed-loop circuit changes, the electric field associated with it also varies. It means that, when the magnetic field in a closed loop of the wire varies, the current, voltage and electric field get induced.
Conclusion:
Therefore, the correct option for the statement "If you change the magnetic field in a closed loop of wire, you induced in the loop a(n)" is option (d).
