Why does a current carrying conductor kept in a magnetic field experience force? What is the direction of force acting on the conductor?
A current carrying conductor contains moving negatively charged particles (i.e., electrons). Each electron experiences a force (= Ben). The total force experienced by electrons is equal to the force experienced by the conductor. This force acts perpendicular to both the magnetic field and the direction of current in the conductor. The direction of the force acting on the conductor is determined by Fleming’s Left Hand Rule.
