Access the official NCERT Class 10 Science textbook for Chapter 12 – Magnetic Effects of Electric Current PDF. This chapter unveils how electric current generates magnetic fields and explores related concepts like the right-hand thumb rule, Fleming’s rules, electromagnets, electric motors and generators, electromagnetic induction, and safety devices in domestic circuits.
Chapter Highlights:
- Oersted’s discovery: Current through a wire creates a magnetic field
- Magnetic field patterns: Straight conductors, circular loops, and solenoids
- Right-hand thumb rule & Maxwell’s cork-screw rule for field direction
- Force on conductor in magnetic field: Fleming’s Left Hand Rule
- Electromagnets: Construction, strength factors, and uses
- Electric motor: Working principle and role of commutator
- Electromagnetic induction: Fleming’s Right Hand Rule, generators
- Domestic electric circuits & safety devices: Fuses, earthing, overload protection
