FAQs on NEET 2025 Electromagnetic Induction and Alternating Currents Mock Test – Chapter-wise Free Practice
1. What is electromagnetic induction?
Electromagnetic induction is the process by which a changing magnetic field within a closed loop induces an electric current in the conductor. This principle is the basis for generating alternating current (AC) in generators and explains many electromagnetic phenomena tested in NEET Physics.
2. State Faraday’s Laws of Electromagnetic Induction.
Faraday’s First Law states that whenever the magnetic flux linked with a circuit changes, an induced emf is produced. Faraday’s Second Law quantifies the induced emf as equal to the negative 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 how does it relate to electromagnetic induction?
Lenz’s Law states that the direction of the induced current is always such that it opposes the cause of its production, i.e., the change in magnetic flux. This law is a manifestation of the law of conservation of energy in electromagnetic induction and appears as the negative sign in Faraday's Law equation.
4. How can you increase the induced emf in a coil?
The induced emf in a coil can be increased by:
- Increasing the number of turns in the coil (N).
- Increasing the speed of relative motion between the coil and the magnet.
- Using a stronger magnetic field.
- Increasing the area of the coil and maximizing the angle of the coil with respect to the field.
5. What is self-induction and mutual induction?
Self-induction refers to the phenomenon by which a changing current in a coil induces an emf in the same coil. Mutual induction occurs when a changing current in one coil induces an emf in a neighboring coil. Both effects are fundamental in transformers and AC circuits, and are frequently tested in NEET Physics.
6. What are alternating currents (AC) and how are they different from direct currents (DC)?
Alternating current (AC) continuously changes its direction and magnitude with time, commonly in a sinusoidal pattern, whereas direct current (DC) flows only in one direction with a constant magnitude. Most household electrical supplies use AC because it is easier to generate, transmit, and distribute over long distances compared to DC.
7. What is the root mean square (RMS) value of AC?
The RMS value of AC is the equivalent value of direct current that would produce the same heating effect in a resistor as the alternating current does over one complete cycle. For a sinusoidal AC, Irms = I0/√2 and Vrms = V0/√2, where I0 and V0 are peak current and voltage, respectively.
8. How is electrical energy transmitted efficiently using transformers?
Transformers are devices based on the principle of mutual induction, used to increase or decrease AC voltage levels for efficient power transmission. High-voltage, low-current transmission minimizes power loss via heat (I²R loss) in the transmission lines, making transformers crucial for the electricity grid.
9. Can you take NEET mock tests for Electromagnetic Induction and Alternating Currents for free on Vedantu?
