Answer:
An electric field is the field associated with a charged body, and it is the extension of the electric charge on the individual subatomic particles that make up the matter in that body. And imbalance in the charges will engender an electric field (an electrostatic field) on the object.
A magnetic field is created as a result of some type of uniform motions of charges. Take the electron, the basic "moving charge" we know so well. When an electron moves (or when any charge particle moves), it generates a magnetic field around its path of travel. Every time. All the time. It cannot be helped. And when electrons move in a conductor, and the conductor is wound around a ferromagnetic core, we create an electromagnetic. (The charges move in only one direction through the coil of an electromagnet.) In a permanent magnet, the ferromagnetic material is formed, and then heated and cooled, the heating and cooling done in the presence of a fixed magnetic field. That field will align magnetic domains (at the atomic level) in the wannabe magnets, and that alignment will be greatly facilitated by heating. By maintaining the static magnetic through the cooling cycle, the magnetic domains that were aligned will then have been "trapped" in position by the cooling.
Both fields are said to be made up of lines of force.
Electric fields (electrostatic fields) can exist by themselves. Magnetic fields exist solely - repeating that - solely because they've been created by some sort of uniform motion of charges. One of the four fundamental forces of the universe is the electromagnetic force. Not the electric force. Not the magnetic force. The electromagnetic force. The two forces are linked in the most profound and fundamental way.
An electric field is a region around a charged object where the object's electric force is exerted on other charged objects.
