CH.4 Magnetic force on current carrying conductor.

When an electric current flows through a conductor placed in a magnetic field, the conductor experiences a force called magnetic force. This force acts perpendicular to both the direction of current and the magnetic field. The phenomenon is the working principle behind electric motors, loudspeakers, and many electrical devices. The direction of the force can be determined using Fleming's Left-Hand Rule. The magnitude of the force is given by: F = BIL sin θ where: F = Magnetic force (N) B = Magnetic field strength (T) I = Current (A) L = Length of conductor in the magnetic field (m) θ = Angle between current and magnetic field This interaction between electricity and magnetism demonstrates the fundamental principles of electromagnetism.
