Sample questions from this chapter

What is the magnetic flux through a plane area A in uniform field B when the field makes angle θ with the area vector?
  1. BA cosθ ✓
  2. BA sinθ
  3. B/A
  4. BA tanθ
Answer: A. Magnetic flux is the scalar product ΦB=B·A=BA cosθ.
Why not B: Using sine treats θ as the angle with the plane rather than with its normal.
Why not C: Flux grows with area instead of varying inversely with it.
Why not D: The dot product of field and area contains cosine, not tangent.
A 0.200 m² loop is in a 0.500 T uniform field. Its area vector makes 60.0° with the field. What flux passes through it?
  1. 0.200 Wb
  2. 0.100 Wb
  3. 0.0500 Wb ✓
  4. 0.0250 Wb
Answer: C. ΦB=BA cosθ=(0.500)(0.200)(0.500)=0.0500 Wb.
Why not A: This multiplies area alone by an implicit 1 T field.
Why not B: This uses BA and omits cos60°.
Why not D: This applies the one-half angular factor twice.
A square loop of side 0.100 m has its area vector at 45.0° to a 0.100 T field. The field falls uniformly to zero in 0.700 s. What emf magnitude is induced?
  1. 1.01×10⁻³ V ✓
  2. 1.43×10⁻³ V
  3. 7.07×10⁻⁴ V
  4. 1.01×10⁻⁴ V
Answer: A. |ε|=BA cos45°/Δt=(0.100)(0.0100)(0.707)/0.700=1.01×10⁻³ V.
Why not B: This uses BA/Δt and omits cos45°.
Why not C: This divides by 1.00 s instead of the stated 0.700 s.
Why not D: This treats the square's area as 0.00100 m² rather than 0.0100 m².

Questions

How many NEET questions are there on Electromagnetic Induction?

This chapter test has 30 questions — 10 easy, 14 medium and 6 hard — all written against the NCERT Class 12 chapter.

Is this NEET Physics chapter test free?

Yes. Every chapter test is free with no login, and you get your all-India rank on every one. Nothing on the site is on sale right now.

Do the questions explain the wrong options?

Yes — every distractor carries its own explanation naming the specific misconception that makes a student pick it. That is the part most question banks skip, and it is the part that changes your next attempt.
