Question

The induced current's direction is such that it opposes the cause of its generation. This is the rule of

• A. Lenz
• B. Faraday
• C. Kirchhoff
• D. Fleming

Answer 1

The correct option is A

Lenz

Explanation for the correct answer:

In the case of Option A,

1. The direction of the induced current is determined by Lenz's law.
2. The induced current, according to this law, it opposes the cause that produces it.

Explanation for the incorrect answers:

In the case of option B,

1. Faraday's law explains how a magnetic field interacts with an electric circuit to generate an electromotive force (EMF).
2. It is represented by $\mathrm{\epsilon }=-\mathrm{N}\frac{\mathrm{\Delta \phi }}{\mathrm{\Delta t}}$.

In the case of option C,

1. "In any closed-loop network, the total voltage around the loop is equal to the sum of all the voltage drops within the circuit," according to Kirchhoff's Voltage Law (KVL).

In the case of option D,

1. According to Fleming's Right-Hand Rule, if we arrange our right-hand thumb, forefinger, and middle finger perpendicular to each other.
2. The thumb points in the direction of the conductor's motion relative to the magnetic field.
3. The forefinger points in the direction of the magnetic field, and the middle finger points in the direction of the induced current.
4. According to Fleming's Left Hand Rule, if we arrange our left-hand thumb, forefinger, and middle finger perpendicular to each other.
5. The thumb points to the direction of the force experienced by the conductor.
6. The forefinger to the direction of the magnetic field, and the middle finger to the direction of the electric current.

Hence, option A is correct.
