"From the axis"? Should be "from the coil plane"? Or a diametric axis?MahalMuh said:
A magnetic field is a region in space where a magnetic force can be detected. It is created by moving electric charges, such as electrons, and is represented by magnetic field lines that show the direction and strength of the field.
A current loop is a closed path through which an electric current flows. When current flows through the loop, it creates a magnetic field around it. The direction of the magnetic field is determined by the direction of the current flow, following the right-hand rule.
The strength of the magnetic field in a current loop is affected by the number of turns in the loop, the amount of current flowing through it, and the radius of the loop. Increasing any of these factors will result in a stronger magnetic field.
The direction of the magnetic field around a current loop follows a specific pattern. As you move away from the loop, the direction of the field changes from pointing towards the center of the loop to pointing parallel to the loop's axis.
The strength of the magnetic field in a current loop can be calculated using the formula B = μ0I/2r, where B is the magnetic field strength, μ0 is the permeability of free space, I is the current flowing through the loop, and r is the radius of the loop. This formula is known as the Biot-Savart law.
