How to Find Direction of Magnetic Field
The direction of the magnetic field due to a current-carrying conductor can be found by applying the rules mentioned below:
- Right-Hand Thumb Rule
- Maxwell’s Corkscrew Rule
Let’s understand these rules in detail as follows:
Right-Hand Thumb Rule
The right-Hand Thumb Rule states that If we hold the conductor in the palm of the right hand and the thumb points in the direction of flow of current, the direction in which the fingers turn gives the direction of the magnetic field lines.
It follows that the magnetic field is in the form of concentric circles, the centers of which are located directly on the conductor.
Maxwell’s Corkscrew Rule
Maxwell’s Corkscrew Rule states that if the right-hand corkscrew is rotated so that it moves in the direction of flow through the conductor, the direction of rotation of the screw gives the edge of the magnetic field lines.
For a current flowing through a conductor in the direction shown in the diagram, both laws predict that the magnetic field lines will be in a counterclockwise direction when viewed from above.
Magnetic Field Lines
Magnetic Field Lines are the imaginary lines around the source of a magnet or any other magnetic substance. Magnetic field lines help us in understanding the behavior of magnetic poles and magnetism. Magnetic fields are the imaginary lines outside a magnet that are helpful to explain the properties of a magnet. In this article, we will explain how magnetic field lines are produced when current flows through a conductor and how they exert a force on any magnetic pole located in the region.
This article aims to provide a complete understanding of magnetic field lines and their properties. So, let’s start learning about Magnetic Field Lines and their properties.
