Magnetic Field Lines


Magnetic field lines are a visual representation of the magnetic field around a magnet or a current-carrying wire. They show the direction of the magnetic field at different points in space and the strength of the field at each point. The magnetic field lines are continuous, forming closed loops that emerge from the north pole of a magnet and enter the south pole. The density of the field lines indicates the strength of the magnetic field, with the lines being closer together where the field is stronger. Magnetic field lines are used in space and astronautical engineering to study the behavior of magnetic fields in space, such as the Earth's magnetic field and the magnetic fields of other planets and stars. They are also used in the design of spacecraft and satellites to protect them from the effects of the space environment, such as solar flares and cosmic rays.
