What is a magnetic field and what is its source?
What is a magnetic field, and what is its source? A magnetic field is a force that is exerted from magnets. Its source comes from movement of charged particles. Every spinning electron is a tiny magnet.
How do magnetic fields get created?
As Ampere suggested, a magnetic field is produced whenever an electrical charge is in motion. The spinning and orbiting of the nucleus of an atom produces a magnetic field as does electrical current flowing through a wire. The direction of the spin and orbit determine the direction of the magnetic field.
Is the magnetic field made of photons?
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).
What is magnetic field and electric field?
A magnetic field is a field explaining the magnetic influence on an object in space. Electric Field. A electric field is a field defined by the magnitude of the electric force at any given point in space. Current. Current is the rate of charge moving past a region.
What type of material can be made magnetic when placed in an external magnetic field?
Materials that can be magnetized are called ferromagnetic materials. They include iron, cobalt, and nickel. Magnetic domains must be lined up by an outside magnetic field for most ferromagnetic materials to become magnets.
Why is a magnetic field created with current?
A magnetic field is generated by an electric current. While an electric charge is moving, this is possible. The magnetic field is generated when the atom spins and orbits the nucleus. The direction of the magnetic field is also dictated by the direction of the electric charge’s spin and orbiting.
Does magnetic field affect photons?
Although a magnetic field doesn’t affect the photons of light directly, a magnet can distort the medium through which light passes and thereby “bend” the light rays. A strong magnetic field can increase the effect of the mass of the object on the curvature of space-time.
How are electric and magnetic fields created?
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.
