Conductor in Magnetic Field

When a wire is suspended between two conductors and carries a current, it deflects from the vertical position in a homogeneous magnetic field as a result of the magnetic force acting on it. This force is perpendicular to both the wire and the magnetic field. The deflection occurs because of the interaction between the magnetic fields of the wire and the external magnets. The discovery of how to produce motion from electricity was made in 1821 by Michael Faraday, laying the foundation for the development of electric motors. The maximum magnetic force occurs when the current and the magnetic field are perpendicular to each other, causing motion at right angles to both the field and the current. The magnitude of the force increases with a stronger current and a more intense magnetic field. J. A. Fleming developed a simple method to determine the direction of this motion, known as Fleming's Left-Hand Rule. If the thumb, first finger, and second finger of the left hand are positioned at right angles to each other, the first finger represents the magnetic Field (from North to South), the second finger represents the direction of the Current, and the thumb indicates the Motion or force on the wire.
