- Concepts, not just answers
A crisp overview, the must-know ideas, and the exam traps for every chapter — distilled from the NCERT, ready in 60 seconds.
- Every formula in one place
Maths, Physics & Chemistry chapters carry a clean formula sheet — no flipping through 40 pages before a quiz.
- Revise, then attempt
It sits right above the quiz — skim it, then test yourself while it's fresh. The exact loop toppers swear by.
Key Concepts
Moving Charges & Magnetism · Class 12 Physics
Magnetic forces act on moving charges and currents. This chapter covers the Lorentz force, the Biot–Savart and Ampère laws, and devices like the solenoid and galvanometer.
- Lorentz force — A moving charge in a magnetic field feels F = qv×B, always perpendicular to its velocity.
- Force on a current — A current-carrying wire feels F = BIL sinθ — the basis of every electric motor.
- Ampère's law — Use it for symmetric fields: a long wire gives B = μ₀I / 2πr.
Key formulas
Lorentz force
F = q(E + v×B)
Field of a solenoid
B = μ₀nI
💡 Exam tips
- The magnetic force does no work — it only changes direction, never speed.
- Use Ampère's law for symmetric cases (wire, solenoid); Biot–Savart for loops.

Common questions, straight answers.
Is XamBaaz free? What does it cost?
You start with a free trial — no credit card needed. After that it's just ₹999 for a full year (a limited-time launch price), with no per-chapter paywalls. Schools can unlock students in bulk with an institute code.
Can my child use it for both board exams and JEE/NEET?
