- 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.
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.
- 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.
