A magnetic field is caused by the movement of electric charges. The magnetic field B is a vector of space and it is defined for every point of space.

Magnetic field and electric current are closely related, since electric current is basically a flow of electric charges. When an electric current I runs through an electric wire, it creates a magnetic field around the wire; the greater the electric current, the stronger the magnetic field.

A magnetic field B, along with an electric field E, creates an electromagnetic force called Lorentz Force, F, on an electric charge q of velocity v:

F = q [E+(v x B)]

where x represents the vector product (or ''cross product'') of v and B.

Magnetic fields have many applications in science, engineering and medicine.

When iron is placed in a magnetic field, some of it's domains line up with the field and the iron becomes magnetized.

its the quatitiy that has both direction and magnitude

the direction of the magnetic field is taken to be the direction in which a north pole of the compass needle moves inside it..

the magnitude line are closed curves.

How does gravity work? How does magnetism work?

Energy can not be created or destroyed. To have energy you must have substance. The substance that causes gravity flows through the 'empty' space inside and in between all atomic particles. Collisions in between matter and the substance that causes gravity (aether) are infrequent, if not impossible.

It is not visible because light does not effect it, sort of how light passes through water. You can not feel it because it is more fluid than any gas. You can see it in solar flares, or when you pick iron pyrite out of the sand with a magnet and watch the iron dance on top of a paper plate while you hold the magnet underneath. A magnetic field is a constant supply of energy that is not potential, but creates kinetic force. Since there is kinetic response without any physical exchange, there must be substance. I call it spirit (wow did I just prove that divinity exists in the universe as a monist state?).

Event horizon is caused by reverse buoyancy effect. A black hole spinning very fast has a close undertow, and when something gets close enough, it is swallowed up. The more mass (atomic particles) an object has, the greater the effect it will have on the aether. Aether moves from positive to negative, or top to bottom, around and around, in and out. This explains why some galaxies have a jet effect. It effects metal (magnetism) because metal has shared electrons. Shared electrons allow current to flow, which explains why power sources can cause phenomena. It is effected by the motion of electrons. Neural pathways also effect this substance, this is why a shark can sense if an organism is living or dead from feet away. The closer to the center of an object you become, the higher the density of mater, and of aether. The higher the pressure of matter, and aether. Reverse buoyancy occurs, causing objects with mass to fall.

Furthermore, an object with less mass is held in orbit by an object with more mass because the larger object has a greater effect on the aether. Velocity also does effect orbit though, this is why the moon is not floating over the same area of the Earth all the time. It is relative.

How do you find the shape of a magnetic field using a compass?

The compass needle will align with the magnetic field. However, if the magnetic field is weak, the magnetic field of the Earth will be stronger, and the magnetic needle will point North.


What is a magnetic field will be produced at some point in space if the electric field at the point?

As far as the electric field is stationary then no magnetic field. But when electric field is moving at a uniform speed then a magnetic field will be produced. This is what we call Lorentz magnetic field.

What is the strength of the magnetic field of a magnet?

The strength of the magnetic field of a magnet varies between magnets. A magnetic field is composed of field lines called magnetic flux lines. The strength of the magnetic field is called flux density and is denoted by the letter 'B'. It is defined as the the magnetic flux passing through a unit of area normal to the field.
