NEET · Physics — Electromagnetism · Maharashtra, India

Physics — Electromagnetism for the NEET Exam — Maharashtra candidates

4% of the NEET test plan. Electric charges, Gauss's law, capacitors, current electricity, magnetism, and electromagnetic induction — approximately 25% of NEET Physics. Calibrated for Maharashtrian candidates.

For candidates aiming to clear this exam on the first attempt, the difference between Band 6 and Band 7+ — or "passing" and "comfortable margin" — usually comes down to fluency on a small number of high-leverage topics. Physics — Electromagnetism sits at roughly 4% of the National Eligibility cum Entrance Test content distribution — Electromagnetism is the second-largest Physics sub-section in NEET, spanning Class 11 (electric charges, current) and Class 12 (magnetism, EMI, AC circuits). NTA NEET Electromagnetism questions are predominantly formula-application; deep derivations are not required. Ohm's law, Kirchhoff's laws, and Faraday's law appear in almost every NEET paper. Pass rates for the NEET are published annually by the awarding body and vary by cohort and locale. For Maharashtra candidates preparing for NEET, the calibration of study to local context matters: Maharashtra hosts the largest single-state JEE Main, NEET, and CET cohorts in India. MHT-CET is the state-level entrance test; many candidates sit JEE Main, MHT-CET, and NEET in the same year.

Pass rates for NEET (Maharashtra, India) are published periodically by the awarding body.

Common failure modes

These are the patterns that cause most candidates to lose marks on this topic. Recognising them in advance is half the work.

  • !Applying Gauss's law to non-symmetric charge distributions
  • !Kirchhoff's junction rule sign errors — currents entering a node are positive, leaving are negative (or vice versa, but the convention must be consistent)
  • !Confusing capacitor charging vs discharging time constants (τ = RC for both, but voltage changes in opposite directions)
  • !Misidentifying the direction of induced current using Lenz's law — forgetting that induced current opposes the change in flux, not the flux itself
  • !Mixing up the force on a current-carrying conductor (F = BIL sin θ) with the force on a moving charge (F = qvB sin θ)

Study tips

  • 1For circuits, master Kirchhoff's two laws: KCL (sum of currents at any node = 0) and KVL (sum of voltages around any closed loop = 0). These are the foundation of all NEET circuit problems.
  • 2Drill Gauss's law for the three NEET-tested geometries: spherical shell, infinite line charge, infinite plane. Know the E-field formula for each.
  • 3Memorise the combination of resistors (series and parallel) and capacitors (series and parallel) — the rules are opposite for R vs C and this swap is a common NEET trap.
  • 4Practice Faraday's law numericals: EMF = −dΦ/dt = −N × d(BA)/dt. Know how to calculate flux for a rectangular coil rotating in a magnetic field.
  • 5For magnetic effects (Biot-Savart, Ampere's law), focus on the finite and infinite straight wire results — these are the most-tested NEET geometries.
  • 6JEE Main and NEET are offered in Marathi (मराठी) at all Maharashtra centres — choose the medium that matches your school instruction medium for best comprehension speed.
  • 7For NEET: Maharashtra State CET Cell runs separate state-quota counselling alongside MCC all-India counselling — register for both to maximise admission chances.
  • 8Mumbai and Pune are the highest-density centres; book test slots within 30 minutes of your home pin code to avoid Mumbai monsoon-season transit delays on test day.

Sample NEET Physics — Electromagnetism questions

These sample items mirror the format and difficulty of real NEET questions. Practice with thousands more on the free Koydo question bank.

  1. 1

    A parallel plate capacitor has plate area A and separation d. Its capacitance is:

    • Aε₀Ad
    • Bε₀A/dCorrect
    • Cε₀d/A
    • Dd/(ε₀A)
    Why this answer?

    The capacitance of a parallel plate capacitor (with vacuum between the plates) is C = ε₀A/d, where A is the plate area, d is the separation, and ε₀ = 8.854 × 10⁻¹² F/m. Inserting a dielectric of constant K gives C = Kε₀A/d.

  2. 2

    Two resistors of 4 Ω and 6 Ω are connected in parallel. The equivalent resistance is:

    • A10 Ω
    • B2.4 ΩCorrect
    • C5 Ω
    • D24 Ω
    Why this answer?

    1/R_eq = 1/4 + 1/6 = 3/12 + 2/12 = 5/12. R_eq = 12/5 = 2.4 Ω. Note: parallel resistance is always less than the smallest individual resistance.

  3. 3

    According to Lenz's law, the induced current in a coil acts to:

    • AEnhance the change in magnetic flux that caused it
    • BOppose the change in magnetic flux that caused itCorrect
    • CMaintain the current magnetic flux constant
    • DReverse the direction of the applied magnetic field
    Why this answer?

    Lenz's law states that the induced EMF (and hence the induced current) is in a direction such that it opposes the change in magnetic flux that produced it. This is consistent with energy conservation — it takes work to move a magnet against the opposing force.

Frequently asked questions

Are AC circuits (resonance, impedance) tested in NEET Physics?
AC circuits (NCERT Class 12 Chapter 7) are in the NEET syllabus. Questions on peak vs rms current/voltage, impedance in series RLC circuits, and resonance frequency (f = 1/(2π√LC)) appear occasionally. However, complex AC circuit analysis (phase diagrams beyond simple series circuits) is JEE-level, not NEET-level.
How many Electromagnetism questions appear in NEET Physics?
NEET Physics has 45 questions. Electromagnetism (including electric charges, current electricity, magnetism, and electromagnetic induction) typically accounts for 10–14 questions — approximately 25–30% of NEET Physics marks.
What is the NEET pass rate for Maharashtrian candidates?
Pass rates for NEET candidates in Maharashtra, India are published periodically by the awarding body. Practice questions, full-length simulations, and weak-area drills are the highest-impact way to improve your odds.
How long should Maharashtrian candidates study Physics — Electromagnetism for the NEET?
For most candidates, focused mastery of Physics — Electromagnetism requires 20–40 hours of deliberate practice — drilling sample questions, reviewing failure modes, and timing yourself against exam conditions. Maharashtra hosts the largest single-state JEE Main, NEET, and CET cohorts in India. MHT-CET is the state-level entrance test; many candidates sit JEE Main, MHT-CET, and NEET in the same year. Combine Physics — Electromagnetism study with full-length mock exams in the final two weeks before your test date.
