According to my understanding of the subject, the magnetic field is associated with the electron and proton fields that are intrinsic to the atomic structures of materials.

The effects that surround the electron have been studied quite extensively, so let us pick that entity as the focal point in further studies. First let us assume that the electron is a fundamental unit.

Definition of the fundamental unit.

A fundamental unit is a structure of mass, that structure has some specific function or purpose for existence. Such as a house could be considered as a fundamental unit for living space. If you break apart such a fundamental unit, then you may discover that it is composed of other fundamental units. Such as a house may be constructed of bricks. Obviously if you break apart any fundamental unit, then that unit no longer can serve the original purpose. Under that line of reasoning, let us consider the electron as a fundamental unit, and try to find out how it functions.

After studying the electron it has become apparent that the electron is a very mysterious object indeed. Besides containing very little mass and lots of energy, the electron also has attributes of charge, spin, gravity, magnetic field, frequency, and according to Einstein's theory acceleration at the speed of light.

I have come up with a bubble theory that will explain most, if not all of these mysterious forces.

Consider the electron as having a round shape, such as a soap bubble, now imagine that the bubble is able to expand and contract to some extreme limits. Suppose that this fundamental super bubble is in the middle of its expansion cycle, as it expands, the surface that contains the bulk of the mass, decreases in density and the velocity of the mass decreases until it comes to a stand still as far as the origin point of the expansion cycle is concerned. As the bubble walls expand, the point where the expansion started has become increasingly empty the emptiness of this area is responsible for the slowing, stopping, and reversing of the velocity vector of the bubble's surface mass. As the bubble begins to contract, the mass of the bubble accelerates due to the potential force that it gained in the expansion phase. The acceleration continues until the density of the mass is so high that it can not increase further, at this point the kinetic energy is at maximum and the mass explodes. At this moment of explosion the expansion phase begins. The acceleration of the bubble's mass is linked to the speed of light when doing calculations concerning the phenomenon.
There is no loss of intrinsic energy in either phase of the cycle, The kinetic energy is totally changed into the potential form and the potential energy is changed totally to kinetic form, therefore the oscillation will continue forever.

The frequency of this explosion/implosion cycle is very high for the electron, slower for the proton and perhaps the universe has a similar, extremely slow, cycle.

The frequency and the charge can be considered as one and the same phenomenon, both can be attributed to the periodic expansion and contraction of the fundamental bubble unit.
The spin of the electron is not very important in explaining magnetic fields because the magnetic phenomenon can be explained without the need for the electron to spin around its own axis.

The charge of the electron or proton is the wave front that is created in the space time continuum by the exploding/imploding process of the fundamental (bubble) unit.
Repelling force is caused by wavefronts that are on the same frequency. Attracting force is caused by two different frequencies that have a certain harmonic and phase relationship.

The magnetic field of atoms arises from the fact that the electrons orbit around the nucleus of the atom. That orbit of the electrons around the nucleus is what gives rise to the angular velocity phenomenon of the charge that is known generally as magnetism. In ferromagnetism the nucleus of the atom is a dipole type structure around which the electrons orbit. In diamagnetic (Diametrically opposed to ferromagnetism) materials the electron orbital vector is in the opposing direction when compared against the dipole nuclei of a ferromagnetic nuclei. In other words, if the two elemental nuclei were arranged side by side with the n pole pointing towards the observer, then in the ferromagnetic material the electrons will orbit in the clockwise direction. Where as in the diamagnetic material the electrons will orbit in the counter clockwise direction. Both ferromagnetic and diamagnetic atoms have a bipolar nucleus. The nuclei of most atoms do not exhibit a bipolar quality.

The Earth's magnetic field is caused by the electrically charged ions that orbit the planet at high altitude. (Van Allen belts)
The electro magnetic fields such as light and radio frequencies are wavefronts created in the space time continuum.

To summarize.
The mass that we are familiar with is composed of a variety of fundamental bubbles of mass. (I prefer to call this fundamental mass that makes up the bubbles by the words kinetic force.) The fundamental bubbles of kinetic force are constantly under the influence of acceleration forces.

Kinetic force bubbles expand and contract at a certain frequency, the frequency is determined by the size of the bubble. For instance, the electron/bubble contains less mass density per unit area than the proton/bubble therefore the electron/bubble has a higher frequency of oscillation.
The bubbles have an outer limit of expansion and an inner limit of contraction. The bubble's expansion and contraction velocity at any instant is determined by the magnitude of the two forces (potential and kinetic) at that particular moment of the bubbles contraction or expansion vector. The bubble or rather the surface of the bubble always experiences acceleration at a constant potential. There are two opposing forces involved in the expansion contraction process. The kinetic force (the mass of the bubble) causes the explosion/expansion process and the potential force (total emptiness) causes the halting of the expansion process and the acceleration in the implosion process.
Empty space contains potential force. Maximum potential force can be considered as an absolute vacuum or total emptiness in these interactions.

PS. I'll be happy to discuss any errors that may be found in this idea.
