Does magnetism exist in vacuum?

Magnets work perfectly in the vacuum – and in the absence of a gravitational field. They don’t depend on any “environment” or “medium”. And the electromagnetic force is independent of gravity, too.

In what direction does magnetic flux travel?

The general direction for the magnetic flux flow is from the North ( N ) to the South ( S ) pole. In addition, these magnetic lines form closed loops that leave at the north pole of the magnet and enter at the south pole. Magnetic poles are always in pairs.

What are the main rules of magnetic flux?

In the most general form, magnetic flux is defined as ΦB=∬AB⋅dA Φ B = ∬ A B ⋅ d A . It is the integral (sum) of all of the magnetic field passing through infinitesimal area elements dA.

What fields can exist in a vacuum?

1) YES, electric fields exist and can extend/propagate through a vacuum. Reasoning: Why not there is no difference between a vacuum and space just that a vacuum has no air in it. Vacuums are still made of matter so the electric field should still extend into that space.

Are magnets stronger in a vacuum?

Yes. Interestingly, electric and magnetic forces are very slightly stronger in a vacuum than in air. Air is slightly polarizable and can move to partially shield the forces.

Why is the magnetic flux through a closed surface zero?

Because magnetic field lines are continuous loops, all closed surfaces have as many magnetic field lines going in as coming out. Hence, the net magnetic flux through a closed surface is zero.

What is the difference between magnetic field and magnetic flux?

Magnetic field describes a region where a magnetic force can be felt. Magnetic flux describes how much magnetic field passes through an area.

Which of the following Cannot travel in a vacuum?

Sound waves do not travel through vacuum.

Can a magnetic field exist in a vacuum?

Yes, magnetic fields can exist in perfect vacuum. I seriously hope that no-one here is suggesting that a magnetic field in a perfect vacuum does not exist, or that a magnetic field un-detected does not exist. Silly me, of course no-one is thinking anything of the sort.

How do electromagnetic waves travel in a vacuum?

Electrodynamic theory grants that electromagnetic waves can travel in vacuum, but where the wave is generated is another thing. It travels on the aether! The magnetic field produces an electric field and in turn electric field produces a magnetic field explanation of propagation is often cited but wrong.

How does an electromagnetic field travel through the air?

from a, b and c: An electromagnetic field is propagating by changing the field that’s generated by electrically charged particles pass through the air and the space that is devoid of particles of space.

Why do electrons not curve in a perfect vacuum?

If you have a perfect vacuum containing a magnetic field, and fire electrons into it, their paths will curve. If you fire electrons under the exact same conditions into a perfect vacuum that has no magnetic field, their paths will not curve.
