Chapter Overview
This chapter explores the magnetic effects of electric charges in motion. You'll learn how currents and moving point charges generate magnetic fields, experience forces (Lorentz force), and move in circular/helical paths. It covers laws like Biot–Savart and Ampère’s law, forces on conductors, torque on loops, and practical devices such as cyclotrons, galvanometers, ammeters, and voltmeters.
Important Keywords
- Magnetic Field (B): Region where magnetic effects occur; SI unit: tesla (T). :contentReference[oaicite:0]{index=0}
- Biot–Savart Law: Calculates B from current elements. :contentReference[oaicite:1]{index=1}
- Ampère’s Law: Relates line integral of B to current enclosed.
- Lorentz Force: F = q(E + v × B); magnetic part F = qvB sin θ. :contentReference[oaicite:2]{index=2}
- Force on Conductor: F = IℓB sin θ.
- Cyclotron: Device that accelerates charged particles using B and oscillating E.
- Magnetic Dipole Moment: μ = NIA for coil.
- Moving‐coil Galvanometer: Measures current via coil torque in B-field.
