Question

State two ways to increase the force on current carrying conductor in a magnetic field. Name a device whose working dePends on the force exerted on a current carrying coil placed in a magnetic field

Answer 1

current carrying conductor placed in a magnetic field experiences a force. If the direction of the field and that of current are mutually perpendicular to each other, then the force acting on the conductor will be perpendicular to both and that can be determined using the Fleming's left-hand rule.
