Names the devices that use current-carrying conductors and magnetic fields?
The devices that use a current-carrying conductor and magnetic fields are given below:
(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.
Name and state the law which is used to determine the direction of force on a current carrying conductor placed in a magnetic field.
(a) Draw a sketch to show the magnetic lines of force due to a current-carrying straight conductor.
(b) Name and state the rule to determine the direction of magnetic field around a straight current-carrying conductor.
