Magnetic fields are produced by electric currents, which can be macroscopic currents in wires, or microscopic currents associated with electrons in atomic orbits. Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge.

There is no fundamental distinction; they are both aspects of one underlying force (the electromagnetic force). The distinction just depends on your frame of reference. Magnetic forces are those forces that come from or affect moving charges, and electric forces are all the rest. Whether you interpret a given force as electric or magnetic depends on your frame of reference  which charges are moving with respect to you, and which are not. It is generally possible for electric forces to be transformed into magnetic forces, and vice versa, by shifting frames of reference.
