Best Answer

A magnetic field is created around the path of travel of any moving charged particle. This is the only way to create a magnetic field, and it is why we call one of the four basic forces in the universe the electromagnetic force. A magnetic field cannot exist without the movement of a charge or charges to create it. Conversely, any charged particle that moves cannot move without creating a magnetic field about its path of travel.

What creates a magnetic field?

Both magnetic materials and moving electric charges induce magnetic fields. "A magnetic field can be created with moving charges, such as a current-carrying wire. A magnetic field can also be created by the spin magnetic dipole moment, and by the orbital magnetic dipole moment of an electron within an atom." A magnetic field can be produced by either a permanent magnet, or an electromagnet, the latter requiring suitable energization to function.
