Is there a magnetic current?

Is there a magnetic current?

Magnetic current (flowing magnetic monopoles), M, creates an electric field, E, in accordance with the left-hand rule.

Do magnetic charges exist?

Our observations shows that a particle with two monopolar properties – an electric charge and a magnetic charge not exist. The search of magnetic monopoles is possible only on high energy physics and scales below the subatomic particles.

Do magnetic field really exist?

However, purely magnetic fields do exist. Therefore, magnetic fields are more than just relativistic electric fields. The correct statement is that electric fields and magnetic fields are both fundamental, both are real, and both are part of one unified entity: the electromagnetic field.

Are magnetic lines real?

No, a magnetic field is not a discrete bunch of lines. Field lines are real in the same sense that the arrows are, or the contour lines on a map. They aren’t just a picture – they genuinely represent something mathematical about the field. But the field lines I choose to draw aren’t unique.

What is the magnetic equivalent of current?

The magnetic flux is analogous to the electric current. 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.

Is magnetism just relativistic?

Actually, magnetism is ENTIRELY a relativistic effect. The force between the two electrons has both an electrical and a magnetic component in the frames which say the electrons are moving. The sum of these two forces isn’t exactly the same as the simple electrical force in the frame where they’re standing still.

Can magnetic field exist without electric field?

No, it is not possible for a magnetic field to exist without an electric field.

Does magnetic flux exist?

Magnetic flux is a measurement of the total magnetic field which passes through a given area. If we use the field-line picture of a magnetic field then every field line passing through the given area contributes some magnetic flux. The angle at which the field line intersects the area is also important.
