Question

From which of the following does the induced current get direction?

• A. By Lenz's law
• B. By left hand rule
• C. By right hand rule
• D. By Ohm's law

Hint:

Remember: Lenz’s law is an application of the law of conservation of energy.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
When current is induced in a conductor due to changing magnetic flux, its direction is determined by physical laws.
Lenz’s Law: States that the direction of induced current opposes the change in magnetic flux that produces it.
Left/Right hand rules: Help determine direction of force or current in a magnetic field, but not directly for induced current.
Ohm’s Law: Relates voltage, current, and resistance, not current direction.
Step 2: Detailed Explanation:
The correct principle for deciding the direction of induced current is Lenz’s law.
Step 3: Final Answer:
The induced current gets its direction by Lenz’s law.
