How do electric currents form?

Answer 1

The magnetic field means there is a charge surrounding a body.

Similarly if we move so much of charge (say electrons as in electricity) we can form a magnetic field.

These electrons if provide sufficient charge around a body magnetic field can easily be developed.

Answer 2

Electricity was formed at the inception of our universe, no one knows how or why. In more relevant terms, though, what we refer to as electricity consists of two main parts:

1)Voltage

2)Amperage

Amperage is how many electrons you have. Electrons are what moves through the wires and actually powers devices. Small devices (i.e. stopwatch, led flashlight) require very little amperage while larger applications (i.e. electric car, Television) require quite a bit more amperage.

Voltage is the difference of charge between where the electrons are, and where they need to go. think of amperage like water in a pipe, and voltage is the pressure.

So to form electricity all one need do is amass many many electrons so as to obtain a net negative charge (the charge of an electron is negative), and there are any number of ways to do this (i.e. hydro-electric plant, gas powered generator, etc.) Electricity is a

kind of energy which is formed when electrons move from one atom to another e.g. when you put a battery in a flashlight electrons move from battery to flashlight and it starts working.

Answer 3

electric currents form when electron moves. Electron movement is considered as electric currents.
