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.

A current-carrying conductor produces a magnetic field around it.
The strength of a magnetic field depends on the current and the distance from the conductor.
Fleming’s Left-Hand Rule is crucial in determining the direction of force on a current-carrying conductor.
A rule to determine the direction of the magnetic field around a current-carrying conductor by pointing the thumb in the direction of the current.
The region around a magnet or current-carrying wire where magnetic force is exerted.
A temporary magnet formed by passing current through a coil wound around a soft iron core, allowing it to be switched ON and OFF.
A rule used to find the direction of force on a current-carrying conductor when placed in a magnetic field.
A device that converts electrical energy into mechanical energy using the interaction between magnetic fields and current.
