Key Laws: Faraday, Lenz, and Their Practical NEET Implications
Faraday’s Law states that a change in magnetic flux induces an EMF in a circuit, which is the foundation of power generation technologies. Lenz’s Law ensures that the direction of this induced EMF always opposes the change, in line with energy conservation required in NEET MCQs.
Understanding these laws assists in visualizing how magnetic flux, coil turns, and speed influence the magnitude and direction of induced current. Practicing mock tests with time tracking reveals typical NEET traps set around these principles, preparing you to avoid common errors.

FAQs on Electromagnetic Induction and Alternating Currents Mock Test 3 for NEET 2025
1. What is electromagnetic induction?
Electromagnetic induction is the process by which an electric current is generated in a closed circuit due to a change in magnetic flux linked with the circuit. This phenomenon is governed by Faraday's laws and is widely used in electrical devices like transformers and generators.
2. State Faraday’s laws of electromagnetic induction.
Faraday’s First Law states that whenever the magnetic flux linked with a closed circuit changes, an emf (electromotive force) is induced in the circuit. Faraday’s Second Law quantifies this: the magnitude of induced emf equals the rate of change of magnetic flux through the circuit. Mathematically, emf = –dΦ/dt, where Φ is magnetic flux.
3. What is Lenz’s law and what is its significance?
Lenz’s law states that the direction of induced current is such that it opposes the change in magnetic flux producing it. This law helps in determining the direction of induced current and ensures conservation of energy in electromagnetic systems.
4. What factors affect the magnitude of induced emf?
Magnitude of induced emf depends on:
• The rate of change of magnetic flux (dΦ/dt)
• Number of turns in the coil (N)
• Strength of the magnetic field (B)
An increase in any of these factors will increase the induced emf as described by Faraday’s laws.
5. What is self-induction and how is it different from mutual induction?
Self-induction is the property of a coil by which a change in current in the coil induces an emf in itself. Mutual induction is when a change in current in one coil induces an emf in a neighboring coil. Self-induction involves a single coil, whereas mutual induction involves two coils.
6. Explain the principle of an AC generator.
An AC generator works on the principle of electromagnetic induction. When a coil rotates in a uniform magnetic field, the magnetic flux linked with the coil changes, inducing an alternating emf according to Faraday’s law. This produces an alternating current (AC).
7. What is meant by root mean square (RMS) value of AC?
RMS value of AC is the effective value of alternating current that produces the same heating effect as a direct current of the same value. It is given by Irms = I0/√2, where I0 is the peak current.
8. How is electromagnetic induction utilized in transformers?
Transformers use mutual induction between two coils (primary and secondary). A changing current in the primary coil induces an emf in the secondary coil, enabling change of voltage levels in AC circuits. This allows for efficient transmission of electrical power over long distances.
9. What type of current is produced by a simple DC generator and why?
A simple DC generator produces a pulsating direct current. This happens because the commutator reverses the connection of the coil with the external circuit every half rotation, ensuring the output current always flows in the same direction.
10. Why do eddy currents occur and how are they minimized in electrical machines?
Eddy currents are circulating currents induced in solid conductors when exposed to changing magnetic fields. They cause energy loss as heat. To minimize them, machines use laminated cores which increase resistance and reduce the magnitude of eddy currents.
11. Can you explain the concept of resonance in an AC circuit?
Resonance in an AC circuit occurs when the circuit's inductive reactance equals its capacitive reactance (XL = XC), resulting in maximum current. This is important for tuning circuits in radios, televisions, and other communication devices.
12. How can practicing NEET chapter-wise mock tests on Electromagnetic Induction and Alternating Currents benefit students?
Practicing NEET chapter-wise mock tests on Electromagnetic Induction and Alternating Currents helps students:
• Strengthen conceptual understanding
• Improve problem-solving speed and accuracy
• Get familiar with NEET question patterns
• Identify weak areas for targeted revision
• Gain confidence through exam-like simulation and instant feedback.
