The magnetic force of an electric current

Magnetic and electrical properties are closely related, as an electric current generates a magnetic field, and a magnetic field produces an electric current as well, and the first to discover the relationship between electric current and magnetic current was the Danish scientist Hans Orsted in 1820 AD when he noticed the deflection of a magnetic needle when it approached From a wire passing through an electric current, and deduced from this that magnetic fields occur as a result of small currents caused by movement within the atoms of the material.


What is magnetic force?


Magnetic force: The effect exerted on either charge by a magnetic field created by the other.


It results from the movement of charges, when two objects that contain a charge that have the same direction of motion (the charge) move, have a magnetic attraction between them.

What are the factors that depend upon the magnetic force acting on a wire with an electric current passing through?


The intensity of the electric current passing through the wire


The intensity of the magnetic flux acting on the wire


Length of the wire


The angle between the magnetic flux and the wire


How to determine the direction of the magnetic force?


The Fleming rule of the left hand is used to determine the direction of the magnetic force acting on a wire through which an electric current passes through, and it states that it states that when the thumb, forefinger and the rest of the finger are placed so that they are all perpendicular and the index finger points to the direction of the field, and the fingers to the direction of the current, the thumb indicates To the direction of the magnetic force.
