DC motor works on the principle of ___ on a current carrying conductor due to magnetic field.
The DC motor is based on the principle that when a current carrying conductor is placed in a magnetic field, it experiences a force.
The force due to the magnetic field on a current carrying conductor is _______ to the magnetic field and_________ to the current.
(a) A current-carrying conductor is placed perpendicularly in a magnetic field. Name the rule which can be used to find the direction of force acting on the conductor.
(b) State two ways to increase the force on a current-carrying conductor in a magnetic field.
(c) Name one device whose working depends on the force exerted on a current-carrying coil placed in a magnetic field.
