NeetVictoryQuestion 1: Faraday's Law and Lenz's Law
The charge that flows through a coil of resistance 4 Ω when the flux through it changes by 0.02 Wb is:
- A 0.5 mC
- B 0.08 C
- C 50 mC
- D 5 mC
Answer: D. 5 mC
Why: Q = ΔΦ/R = 0.02/4 = 5 × 10⁻³ C.

Question 2: Self and Mutual Inductance
If the number of turns of a solenoid is doubled, keeping its length and area the same, its self-inductance becomes:
- A half
- B unchanged
- C four times
- D two times
Answer: C. four times
Why: L = μ₀N²A/l ∝ N², so doubling N multiplies L by 4.
Question 3: Faraday's Law and Lenz's Law
The SI unit of magnetic flux is the:
- A weber
- B gauss
- C tesla
- D henry
Answer: A. weber
Why: 1 Wb = 1 T m². The tesla is the unit of magnetic field and the henry that of inductance.
Question 4: Self and Mutual Inductance
The self-inductance of a coil depends on:
- A the current flowing through it
- B the number of turns, area, and core material of the coil
- C the voltage applied only
- D the color of the wire
Answer: B. the number of turns, area, and core material of the coil
Why: Self-inductance L = μN²A/l depends on the geometric and material properties of the coil (turns, area, length, permeability of the core) — not on the current through it.
Question 5: Faraday's Law and Lenz's Law
A rod of length 0.5 m moves at 5 m/s on rails in a field of 0.4 T. The circuit resistance is 2 Ω. The force needed to keep it moving at constant speed is:
- A 0.01 N
- B 0.5 N
- C 0.1 N
- D 1 N
Answer: C. 0.1 N
Why: ε = Blv = 1 V, I = 0.5 A, and F = BIl = 0.4 × 0.5 × 0.5 = 0.1 N.
Question 6: Self and Mutual Inductance
The time constant of an LR circuit with L = 2 H and R = 10 Ω is:
- A 0.2 s
- B 5 s
- C 20 s
- D 0.5 s
Answer: A. 0.2 s
Why: τ = L/R = 2/10 = 0.2 s.
Question 7: Faraday's Law and Lenz's Law
A loop of area 0.5 m² is placed in a uniform magnetic field of 0.2 T with its normal at 60° to the field. The magnetic flux is:
- A 0.2 Wb
- B 0.1 Wb
- C 0.087 Wb
- D 0.05 Wb
Answer: D. 0.05 Wb
Why: Φ = BA cosθ = 0.2 × 0.5 × 0.5 = 0.05 Wb.
Question 8: Self and Mutual Inductance
An inductor in a circuit:
- A stores charge
- B does not affect the current
- C opposes any change in the current through it
- D opposes the current itself
Answer: C. opposes any change in the current through it
Why: It plays the role of inertia for electric current.
