Electromagnetism is the division of physics that studies the relationships between electric and magnetic phenomena, that is, the interactions between charged particles and electric and magnetic fields.
Compass – electromagnetism – magnetic field
Compasses work by electromagnetism.
Electromagnetic singularities have critical applications in engineering, electronics, health, aeronautics, or civil construction. Moreover, they look in daily life, almost without realizing it, in compasses, speakers, doorbells, magnetic cards, hard drives.
Electromagnetism allows the use of devices such as microwaves or television.
Electromagnetism is very useful for human beings since countless applications allow them to satisfy their needs. Also many instruments are cast-off daily work due to electromagnetic belongings. The electrical current that mixes through all the connections in a house, for example, delivers many uses (the microwave oven, the fan, the blender, the television, the computer ) that exertion unpaid to electromagnetism.
Magnetism is the singularity that explains the force of attraction or repulsion between magnetic materials and moving charges.
Electromagnetism involves physical phenomena produced by electrical charges at rest or in motion, which give rise to electric, magnetic or electromagnetic fields, affecting the matter in a gaseous, liquid, and solid state.
magnetic arena, and that goods an electric current compared to the sound conventional. Earthworks like a giant magnet due to the magnetic field generated in its core (formed by metals such as iron-nickel ). The rotational movement of the Earth generates a current of charged particles (the electrons of the atoms of the Earth’s nucleus). This current produces a magnetic field that extends several kilometres above the planet’s surface and repels harmful solar radiation.
It is a physical phenomenon by which objects exert forces of attraction or repulsion on other materials. The only natural magnet is a mineral called lodestone. However, all materials are part of the presence of a magnetic field. Therefore, it is easier to detect magnetic properties in some, for example, nickel, iron or cobalt.
Magnets are used by medical science too. For example, they measure brain activity through magnetoencephalography (MEG). Magnets are materials that exhibit the properties of magnetism. They can be natural, like magnetite or artificial—classified as permanent or temporary. For example, poles repel each other, while differing poles attract each other. This effect has to do with magnetic field lines.
It is a sensory, physical field in which electrical particles produced by electrically charged bodies or objects interact. In such a field, there is a quantity of electromagnetic energy. But to better understand the concept, it is essential to know how and why the electric field and magnetic.
The electric field occurs when there are differences in voltage, and the higher it is, the greater the area will exist. So then, the space where the electrical forces act—knowing the extent of the electric field will allow understanding the level of intensity and what happens to a charge in a specific part of the field, regardless of not knowing what causes it.
The magnetic field originates in electric currents, and the greater the current, the greater the area. It is the magnet’s agitation to the region around it, how it affects it, and also in what direction. It represented field lines that go outside the magnet’s north pole to the south pole and by its inside from the south pole to the north pole.
It is the set of electromagnetic energies of the waves. The electromagnetic radiation ranges from those with shorter wavelengths (X-rays, gamma rays), ultraviolet radiation, light and infrared radiation to those with longer wavelengths Length (radio waves).
The spectrum of an object or fluid will be the characteristic distribution of its electromagnetic radiation. There is a theory that the shortest wavelength limit is approximately the Planck length (a measure of subatomic distance), and the long-wavelength upper limit is the size of the universe itself, even though the spectrum is continuous and infinite.
They are the waves that do not need a material medium for their propagation to travel through a vacuum and at a constant speed of 299,792 kilometres per second. Also several examples of these waves are light, microwaves, X-rays, and television and radio transmissions.
The radiations of the electromagnetic spectrum present curving (deviation when achieving an opaque object). Interference (superposition of waves) is the specific property of wave motion.
The application of electromagnetic waves has had a substantial impact on the world of telecommunications by making wireless communication possible through radio waves.
It is the propagation of electric and magnetic particles oscillating, and where each one generates a field (electric and magnetic). This radiation causes electromagnetic waves that can propagate through air and vacuum.
