A dynamo.
It is hard to produce pure direct current using the induction of a magnet on a coil.
In a rotating coil the north and south poles of a magnet will normally cause the current to flow the opposite way, every half turn.
In a dynamo, the spinning electromagnet in the centre of the field coils, has many separate windings. The current is switched to each coil make sure the magnetism only has one polarity, at each fraction of a turn. This switch is called a commutator.

What type of current does a storage battery porduce?
A storage battery produces direct current (DC). This type of current flows in a constant direction from the positive terminal to the negative terminal of the battery.
Do batteries provide a DC voltage or an AC voltage?
Batteries produce DC because the potential difference is determined by the chemical reaction inside the battery. This voltage is constant.
What type of current will a circuit that involves a battery and electrons traveling in one direction have?
a battery always produces a direct current.the electrons always travel from the negetiove to the positive terminal.But the direction of the current is the opposite that is from the positive to the negetive terminal.
What are 4 types of DC voltage?
There is only 1 type of DC voltage, and that is direct current. In order to better answer your question, you need to be more specific.
What is the SI unit for direct current?
The SI unit of EMF (electromotive force) in a direct current circuit is Volts. The circuits current is measured in ampere's
What does the term rectifier mean?
An electrical device that converts alternating current to direct current is known as a rectifier. An inverter is a device that converts direct current to alternating current.
What piece of equipment is used to produce electricity?
Some possible answers are: a battery (which produces direct current) or a generator of electricity generator, such as a dynamo (which produces direct current) or an alternator (which produces alternating current).
Which device is used to convert direct current into alternating current?
An inverter
How does a device convert direct current (DC) to alternating current (AC)?
A device called an inverter is used to convert direct current (DC) to alternating current (AC). The inverter switches the direction of the current flow at a rapid rate, creating an alternating current output from the direct current input.
What is an ac and DC generator?
An a.c. generator produces alternating current, whereas a d.c. generator produces direct current.
What kind current is produced by a dry cell?
A dry cell produces direct current (DC) when a chemical reaction within the cell generates a flow of electrons in one direction. This current flows from the negative terminal to the positive terminal of the cell.
Which device you use to convert the direct current into AC?
Invertor
Which is the device that converts AC to DC?
A Rectifier converts Alternating current into Direct current
What device has the ability to change direct current to alternating current?
It's called an inverter.
Does a dry-cell battery produce the same current that a generator produces?
A dry cell produces direct current, which means that the current flows from one terminal of the dry cell to the other in one direction only. The word generator nowadays often means a device that produces alternating current, which is to say current that reverses its direction, usually at a fixed rate called the frequency. For instance, the current available in North American homes is alternating current at 60 cycles per second; it reverses direction 120 times per second. A machine that produces current that resembles what is available from a dry cell is often called a dynamo. These devices are similar to generators but with switches in them to change the alternating current to direct current, in effect. The current they produce is still not quite like that from a dry cell inasmuch as it's not perfectly 'smooth' continuous direct current. There's a ripple of slightly higher and lower current superimposed on the direct current. Please see the link, especially the graph associated with the Gramme dynamo.
Is it true that a battery produces alternating current?
No. A battery produces DC, or Direct Current.
Does a dry cell battery produce alternating current or direct current?
directA dry cell battery produces DC.
