Electromagnetism studies the interactions found in electric charges that are expressed by electric fields and magnetic fields connected to each other. Both electric and Strong Neodymium Magnets suppliers fields have electric charges.

　　The interactions of electromagnetism were discovered in 1821, thanks to the British scientist Michael Faraday who with the help of James Clerk Maxwell completed the phenomenon in 1865.

　　Types of electromagnetism that exist

　　Electrical charges are central to magnetic and electromagnetic forces. The difference between magnetic and electromagnetic forces is the charge dynamics of each. The electric force and the magnetic force are produced with moving charges, the difference is that the static force in addition to this way of obtaining these charges, can also obtain them with static charges. On the other hand, the electric force has the ability to condition charged particles in motion or stationary, while the magnetic force only creates influence on moving charges.

　　Electrical phenomena do not only remain in natural phenomena and anthropic phenomena, but are also found in atoms. These subatomic particles give stability to the various properties of a material.

　　It should be noted that the magnetic force is also present in all atoms (diamagnetism), with the electric force is lower. As soon as the presence of unpaired electrons appears, we find paramagnetism, which is a higher force. Paramagnetism depends on interactions between some atoms and molecules, in other words, it does not occur in individual atoms. The molecules that generate these interactions are the basic components of magnets.

　　Uses and applications of electromagnetism

　　Electromagnetism can be found in several sectors such as: engineering, electronics, aeronautics, medicine… We can also find applications of electromagnetism in daily life in:

　　Bells: The bell through an electromagnet receives an electric charge that produces a magnetic field attracting a kind of hammer with a metal. Subsequently the noise is produced due to the shock.

　　Microwave: This appliance produces electromagnetic radiation that vibrates the water molecules found in the food, which generates heat for cooking the food.

　　Microphone: This instrument through a membrane is attracted by a magnet inside a magnetic field producing sound in an amplified form.
