Tell about Electric Currents ?

Its units is coulomb. Current: It is the "flow" of electrons from higher electric potential towards the lower.

They also create magnetic fields, which are used in motors, inductors and generators.

As the magnet turns, an electric current is produced in the wire.

When a wire or any electrically conductive material moves across a magnetic field,

The moving charged particles in an electric current are called charge carriers.

an electric current is produced in that wire.

In metals, one or more electrons from each atom are loosely bound to the atom, and can move freely about within the metal.

The spinning rotator coil continually interrupts the lines of force of the magnetic field,

These conduction electrons are the charge carriers in metal conductors.

producing electrical current.

A sufficient electromotive force (emf), or voltage

The conventional symbol for current is I, which originates from the French phrase intensité du courant, (current intensity)

produces a charge imbalance that can cause electrons to move through a conductor as an electric current,

according to Serif Uran,

Current intensity is often referred to simply as current

a professor of physics at Pittsburg State University.

This is what happens in the case of electrical current in a wire

The I symbol was used by André-Marie Ampère, after whom the unit of electric current is named, in formulating Ampère's force law (1820

heating effect,

The notation travelled from France to Great Britain, where it became standard, although at least one journal did not change from using C to I until 1896

chemical effect,

In a conductive material, the moving charged particles that constitute the electric current are called charge carriers.

magnetic effect.

An electric circuit is like a pathway made of wires that electrons can flow through.

In metals, which make up the wires and other conductors in most electrical circuits, the positively charged atomic nuclei of the atoms are held in a fixed position, and the negatively charged electrons are the charge carriers, free to move about in the metal.
