What does the magnetic field around a moving charge look like?
A magnetic field is an invisible force that surrounds a magnet or a moving electric charge. It is represented by magnetic field lines, which show the direction and strength of the magnetic force.
Magnetic fields are created when charged particles, such as electrons, move through a conductor. The motion of these charges creates a circular pattern of magnetic field lines around the conductor.
An electric field is created by stationary charges, while a magnetic field is created by moving charges. Additionally, an electric field exerts a force on other charges, while a magnetic field only exerts a force on moving charges.
The strength of a magnetic field decreases as you move further away from the source of the field. This decrease follows an inverse square law, meaning that the strength decreases exponentially as the distance increases.
Magnetic fields have many practical applications in everyday life. They are used in electric motors, generators, and MRI machines. They are also used in compasses to determine direction and in credit cards to store information.
