It is stated that a force is experienced by a current carrying conductor when placed in the magnetic field.  

This is stated by the French Scientist Andre Marie Ampere.Force is changed when direction of current and magnetic field through the conductor is changed.Force is experienced maximum when the Current and Magnetic field are at right angle.
Fleming left-hand rule:- Thumb = Direction of Motion or Force acting on conductorFore (First) finger = Direction of Magnetic field
Middle (Second) figure = Direction of Current in conductor
1.     Electric motor, Electric Generator, Loudspeakers, Microphones, and Measuring instruments.
2.    Magnetic Resonance Imaging (MRI) technique is used to obtaining the images of different body parts by
using body magnetic field which is produce by ions.
