10. Electro Magnetism

Electromagnetism introduces the magnetic effects of electric current and outlines how various configurations of current-carrying conductors generate magnetic fields. Key principles such as the Right-Hand Thumb Rule and Fleming’s Left-Hand Rule help determine the direction of current and force in magnetic fields. Applications of electromagnetism are pervasive in devices like electric motors, solenoids, and electromagnets.
