There are actually two general types of electromagnetic forces: electrostatic forces and magnetic forces.

['The magnetic field at any given point is specified by both a direction and magnitude.', 'Magnetic lines of force start from the North Pole and end at the South Pole outside magnet.', 'Two magnetic lines of force cannot intersect each other and they are continuous along the axis of the electromagnetic conductor.']

The electric field is produced by stationary charges, and the magnetic field by moving charges (currents); these two are often described as the sources of the field. The way in which charges and currents interact with the electromagnetic field is described by Maxwell's equations and the Lorentz force law.

Meanwhile, the electromagnetic force is the name of force in Maxwell's equations, in which he showed that the force of magnetic attraction and the force of electrostatic attraction were two parts of a ... Electromotive force is measured in volts (so it is the technical name for what most people just call the voltage).

There are many types of electromagnetic waves. From lowest energy to highest energy (red to blue) there are radio waves, microwaves, infrared, visible light, ultraviolet, x-rays and gamma rays.

Electromagnetic waves are created by the vibration of an electric charge. This vibration creates a wave which has both an electric and a magnetic component. An electromagnetic wave transports its energy through a vacuum at a speed of 3.00 x 108 m/s (a speed value commonly represented by the symbol c).

Of course it is logical, EMF stands for Electro-Motive Force and force is normally measured in Newtons. EMF on the other hand, is the electric force needed to move electrons (usually) through a wire.

magnetic circuits In magnetic circuit. The magnetomotive force, mmf, is analogous to the electromotive force and may be considered the factor that sets up the flux. The mmf is equivalent to a number of turns of wire carrying an electric current and has units of ampere-turns.

All of the light from the Sun and other sources consists of photons which are the electromagnetic force carriers. Magnets and the Earth's magnetic field, which protects us from harmful radiation, are aspects of the electromagnetic force.

An electromagnetic wave (such as light) has both an electric and magnetic component. The two components of the wave travel in the same direction, but oriented at a right angle (90 degrees) to one another. Like electricity, magnetism produces attraction and repulsion between objects.

Electric fields are produced by two kinds of charges, positive and negative. Magnetic fields are associated with two magnetic poles, north and south, although they are also produced by charges (but moving charges).

Electromagnetic waves are typically described by any of the following three physical properties: frequency (f), wavelength (λ), or intensity (I). Light quanta are typically described by frequency (f), wavelength (λ), or photon energy (E).

The gravitational force, spring force, magnetic force (according to some definitions, see below) and electric force (at least in a time-independent magnetic field, see Faraday's law of induction for details) are examples of conservative forces, while friction and air drag are classical examples of non-conservative ...
