FAQs on Electromagnetic Induction and Alternating Currents Mock Test for NEET 2025
1. What is electromagnetic induction?
Electromagnetic induction is the process by which a changing magnetic field induces an electric current or emf (electromotive force) in a nearby conductor. This is governed by Faraday's Law and is a fundamental concept for generators, transformers, and many NEET Physics questions.
2. State Faraday’s laws of electromagnetic induction.
Faraday's laws state: (1) Whenever magnetic flux linked with a circuit changes, an induced emf is generated in the circuit. (2) The magnitude of induced emf is directly proportional to the rate of change of magnetic flux through the circuit, symbolized as emf = -dΦ/dt, where Φ is magnetic flux.
3. What is Lenz’s Law and how does it relate to the direction of induced current?
Lenz's Law states that the induced current always flows in a direction such that it opposes the change in magnetic flux that caused it. This is expressed by the negative sign in Faraday's law and helps determine the direction of induced current in NEET problems.
4. What factors affect the magnitude of induced emf in a coil?
The magnitude of induced emf in a coil depends on: (1) The rate of change of magnetic flux, (2) The number of turns in the coil, and (3) The orientation of the coil with respect to the magnetic field. Faster changes, more turns, and optimal orientation all increase emf.
5. How does a transformer work on the principle of electromagnetic induction?
A transformer works on the principle of mutual induction where a changing magnetic flux in the primary coil induces an emf in the secondary coil. The voltage ratio depends on the number of turns in the primary and secondary coils.
6. What is self-induction and mutual induction?
Self-induction refers to the phenomenon where a changing current in a coil induces an emf in the same coil, while mutual induction refers to the emf induced in a neighboring coil due to the change of current in the first coil. Both are important in NEET Physics and circuit analysis.
7. What is eddy current and give two practical applications?
Eddy currents are circular electric currents induced in conductors by a changing magnetic field. Applications include electromagnetic braking, induction heating, and energy meters. Laminated cores are used in machines to reduce energy loss due to eddy currents.
8. Why are cores of transformers laminated?
Transformer cores are laminated to reduce eddy current losses. Lamination increases resistance to these currents, thereby minimizing unwanted heating and increasing efficiency of the transformer.
9. What is alternating current (AC) and how does it differ from direct current (DC)?
An alternating current (AC) periodically reverses direction with time, while direct current (DC) flows in a constant direction. Most household power supplies use AC, while batteries supply DC.
10. What is the phase difference between current and voltage in a purely inductive AC circuit?
In a purely inductive AC circuit, the current lags the voltage by 90° (π/2 radians). This phase relationship is important for analyzing AC circuits in the NEET exam.
11. How can I use NEET chapter-wise electromagnetic induction mock tests to improve my score?
Chapter-wise NEET mock tests for electromagnetic induction help you practice all key concepts, evaluate your weak areas, and track your progress with instant solutions. Consistent practice of these topic-based MCQs is proven to boost accuracy and scores in the actual exam.
12. Can I download a PDF of electromagnetic induction worksheets with answers for revision?
Yes, most NEET preparation portals and study apps provide downloadable electromagnetic induction worksheets with answers in PDF format. These worksheets are helpful for offline practice, last-minute revision, and refer to correct solutions to strengthen exam readiness.
