An electric current is created when a wire moves between the poles of a magnet.
So, option A is correct.
What is Electric current?
- The movement of positive or negative electric particles such as electrons through electric conductor or space is called electric current.
- Types of electric current are direct current (DC) and alternative current (AC)
- The SI unit of electric current is Ampere.
- The poles of a magnet creates magnetic field through such effect the movement of electrons in the wire starts and creates electric current.
What is direct current (DC) ?
- The current which glows in only one direction consistently is called direct current.
- The current that flows in a flashlight or another appliances which run through a battery is an example of direct current.
What is alternative current (AC)?
- A type of electric current in which the direction of the flow of electrons switches back and forth at regular interval or cycles.
- Current flows in power line is an example of alternative current.
