There is a small permanent magnet attached to the bottom of the battery. The field lines are symmetric about that permanent magnet.rumborak said:Why would the field lines not be radially symmetric around the battery? And, why would they "exit" at the bottom like that?
Faraday's motor is an electromagnetic device that converts electrical energy into mechanical energy. It works by utilizing the principle of electromagnetic induction, where a magnetic field is created by passing an electric current through a wire, and this magnetic field interacts with another wire to create a force that causes circular motion.
The wire is placed in between the poles of a permanent magnet. When an electric current is passed through the wire, it creates a magnetic field around the wire. This magnetic field interacts with the magnetic field of the permanent magnet, causing a force that makes the wire move in a circular motion.
The commutator is a crucial component of Faraday's motor as it helps to reverse the direction of the electric current in the wire. This reversal of current ensures that the wire continues to move in a circular motion as it passes through different poles of the permanent magnet.
No, Faraday's motor requires a magnet to work. The magnetic field produced by the permanent magnet is essential for creating the force that causes the wire to move in a circular motion.
Faraday's motor is different from other types of motors because it uses electromagnetic induction to convert electrical energy into mechanical energy, whereas other motors may use different mechanisms such as electromagnetism or electromagnetic attraction and repulsion.
