You asked: What particles make up a magnetic field?

In a moving reference frame, a magnetic field appears instead as a combination of a magnetic field and an electric field, so electric and magnetic fields are made of the same “stuff” (photons). Some electromagnetic interactions involve “real” photons with definite frequencies, energies, and momenta.

Is magnetism a particle?

Magnetism is a transverse wave caused by the spin of a particle such as an electron or proton. … The entire particle spins, so it creates these waves in different directions as it spins.

Are photons affected by magnetic fields?

According to theory of properties of photon, they can not be affected by electric and magnetic fields and it is neutral. But Electromagnetic waves contain electric and magnetic fields .

What is a magnetic field and what is its source?

Magnetic fields are produced by electric currents, which can be macroscopic currents in wires, or microscopic currents associated with electrons in atomic orbits. The magnetic field B is defined in terms of force on moving charge in the Lorentz force law.

What three elements make up a magnetic field?

Iron, cobalt and nickel, elements number 26, 27 and 28 respectively on the periodic table, are considered the elements with the strongest magnetic…

How magnetic field is created?

Any current (movement of electrical charge) will create a magnetic field. Certain materials are capable of realigning the angular momentum of their electrons, and iron is one of them. When the angular momentum of electrons gets aligned, an external magnetic field is created.

Do magnetic fields have mass?

magnetic fields are produced by charged particles in motion, and depend on the charge and velocity of these particles, but not on their mass.

Can light be deflected by magnetic fields?

So there is no way that a magnetic field can bend light. … For instance, if the object is very small (small compared to the wavelength of the light), the light will simply diffract around the object and be invisible or nearly so anyway.

Are photons affected by electric field?

According to theory of properties of photon, they can not be affected by electric and magnetic fields and it is neutral. But Electromagnetic waves contain electric and magnetic fields .

What exactly is a magnetic field?

The magnetic field is the area around a magnet that has magnetic force. All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other.

Does magnetic monopole exit?

If there are charges, then magnetic field will be created due to their movements. A magnetic monopole does not exist. Just as the two faces of a current loop cannot be physically separated, magnetic North pole and the South pole can never be separated even on breaking a magnet to its atomic size.

Why is B used for magnetic field?

What is the historical reason for denoting magnetic filed “B”? … A is still used for vector potential, B for magnetic field (or magnetic induction or flux density, depending who you ask), H for magnetic intensity, etc. Maxwell used C and G for other vectors that I don’t recall at the moment.

Why do like poles repel?

Like-poles repel: We can use curvy arrows (called field lines) to draw the shape of the magnetic field around magnets. … When two like-poles point together, the arrows from the two magnets point in OPPOSITE directions and the field lines cannot join up. So the magnets will push apart (repel).

What is the difference between B and H?

Electric current I produces around itself magnetic field strength “→H” (also called as “Magnetic field intensity”) regardless the type of the surrounding medium. “Magnetic Flux density” “→B” is a response of the medium to the applied excitation →H.

What are the 4 magnetic metals?

  • Nickel.
  • Cobalt.
  • Some alloys of rare earth metals.
