It's called a 'split-ring commutator'. It changes the naturally-produced a.c. into d.c.

How can you reverse the direction of the magnetic field in a wire produced by an electric current?
You can reverse the direction of the magnetic field by reversing the direction of the electrical current.
What is the meaning of altering current?
An electric current that reverses its direction many times a second at regular intervals, typically used in power supplies.
What is the role of split rings in electric motors?
Split rings keep the current flowing in the same direction or the motor turning in the same direction when using alternating current which reverses direction in its cycle..
What is the definition of AC generator?
An electric device that produces an electric current that reverses direction many times per second. Also called a synchronous generator.
How does electricity generate magnetism?
A flow of electric current creates a surrounding swath of magnetic flux. This flux will mingle with and surround the current flow. If the current is bent by say winding a wire in the form of a coil, the flux will shape itself around the coil. The strength of the flux will vary with the current. Reversing the current reverses the flux direction.
What is AC current?
An AC current (alternating current) is one that changes its direction continuously - typically at 50 or 60 Hertz (cycles per second).
What is the definition of commutator?
A commutator is an electrical switch that periodically reverses the current direction in an electric motor or electrical generator. A commutator is a common feature of direct current rotating machines.
What happens when the electric current is reversed on am electromagnet?
When an electric current is reversed in an electromagnet, the magnetic field also reverses.
When current flow reverses itself several times per second that type of electric current flow is called what?
When the current in a conductor reverses direction periodically, that type of currentis categorized as "Alternating Current" (AC).Whether the reversals occur several times per second or once a month is irrelevant.
What are the differences between AC power and DC power?
The description AC/DC refers to equipment designed to be operate on either alternating current (AC) or direct current (DC). In alternating current the movement of electric charge periodically reverses direction. In direct current , the flow of electric charge is only in one direction.
In which circuit does charge reverse direction many times per second?
In an alternating current (AC) circuit, the electric charge periodically reverses direction at a certain frequency. This is in contrast to a direct current (DC) circuit, in which charge flows in one direction only.
When current in a circuit reverses its direction in a regular pattern it is called?
An "Alternating Current" (AC).
