An electric field surrounds an electrically charged particle, while a magnetic field is a region of magnetic influence, typically around a magnet or a moving electric charge.<ref name="ref1" /><ref name="ref2" /><ref name="ref3" /> Electric and magnetic fields are two aspects of the same phenomenon, known as the electromagnetic field.<ref name="ref4" /> A changing electric field can create a magnetic field, and a changing magnetic field can create an electric field.<ref name="ref4" /><ref name="ref5" /> This relationship is described by Maxwell's equations, which are a set of fundamental equations that form the basis of classical electromagnetism.

=== Nature of the Fields ===
Electric fields are produced by electric charges.<ref name="ref1" /> The strength of an electric field depends on the magnitude of the charge creating it. The direction of the electric field is defined as the direction of the force that would be exerted on a positive test charge. Consequently, electric field lines radiate outwards from positive charges and inwards toward negative charges.<ref name="ref3" />

Magnetic fields are generated by the movement of electric charges, such as an electric current in a wire, or by magnetic materials. The magnetic field lines of a magnet are directed from the north pole to the south pole. Unlike electric field lines, magnetic field lines always form closed loops.

=== Interaction with Charged Particles ===
A key difference between the two fields lies in their interaction with charged particles. An electric field exerts a force on any charged particle within it, whether it is stationary or moving. In contrast, a magnetic field only exerts a force on a charged particle when it is in motion.<ref name="ref5" /> This magnetic force is always perpendicular to both the velocity of the particle and the direction of the magnetic field itself. Because the magnetic force is perpendicular to the particle's motion, it changes the direction of the particle's velocity but does not change its speed or kinetic energy; therefore, a magnetic field does no work on a free charge. An electric field, however, can perform work on a charge, altering its kinetic energy.

=== Relationship and Electromagnetism ===
Electric and magnetic fields are intrinsically linked. A changing magnetic field induces an electric field, a principle known as Faraday's law of induction, which is the basis for electric generators.<ref name="ref4" /> Conversely, a changing electric field generates a magnetic field.<ref name="ref4" /> This interplay is fundamental to the propagation of electromagnetic waves, such as light, where oscillating electric and magnetic fields are perpendicular to each other and to the direction of wave travel. The complete relationship between electric and magnetic fields, charges, and currents is encapsulated in Maxwell's equations.
