In physics, a magnetic field is that part of the electromagnetic field that exerts a force on a moving charge. A magnetic field can be caused either by another moving charge (i.e., by an electric current) or by a changing electric field.

Magnetic Field,. The term magnetism comes from the region of Magnesia, a city in Western Turkey, where Greeks found lodestones, which attracted iron pieces across the space. It is also observed that, magnets attract as well as repel. We can explain this dual nature of magnetic force by proposing that each magnet has two ...

The Sun's magnetic field lines get tangled over time as the Sun rotates. These tangled magnetic fields give rise to sunspots and solar activity such as solar flares and Coronal Mass Ejections (CMEs). Credit: SOHO (ESA & NASA). The Sun is not solid. It is a huge sphere of plasma, so it behaves like a gigantic ball of gas.
