When a charge is rest w.r.t me no magnetic field is produced but when it moves w.r.t me then there exists a magnetic field, how?

w. r. t observer and then how?
A magnetic field is an area of space surrounding a magnet or electric current in which magnetic forces can be detected. It is created by the movement of electrically charged particles, such as electrons.
An electron has an inherent property called spin, which generates a magnetic dipole moment. This dipole moment creates a magnetic field around the electron, with the direction of the field determined by the direction of the electron's spin.
The strength of the magnetic field due to an electron is directly proportional to the magnitude of the electron's spin. The higher the spin, the stronger the magnetic field will be. Additionally, the distance from the electron also affects the strength of the field, as it decreases with distance.
The direction of the magnetic field due to an electron is determined by the right-hand rule. If the thumb of your right hand points in the direction of the electron's spin, then the curl of your fingers gives the direction of the magnetic field.
The magnetic field due to an electron is used in a variety of technologies, including compasses, electric motors, and MRI machines. It is also important in understanding the behavior of charged particles in space and in the Earth's magnetic field.
