A magnetic field is an invisible field that exerts a magnetic force on substances that are sensitive to magnetism.
Many people think of magnetism as a property of metal, particularly iron, since common household magnets are made from iron. Magnetic fields have many properties that scientists and others have used over the centuries. Medicine uses it in things like diagnostic machines such as Magnetic Resonance Imaging (MRI) equipment. Can wood or certain timber types alter or have influence to change a magnetic field in anyway enhanced by vibration, i.e.
All you need to perform this experiment is two pieces of wire, a battery, a coil of wire and a compass.
Physicist: Magnetic fields are nothing more than the result of combining an electric field with the effects of relativity.
In addition to creating magnetic fields, moving charges also experience force from a magnetic field that can be found using another right hand rule.  Point your fingers (on your right hand, of course) in the direction the charge is moving, curl your fingers in the direction of the field, and your thumb will be pointing in the direction of the force. But this all begs the question; how fast do the particles have to be moving so that the magnetic field they generate to pull them together is strong enough to balance the electric force pushing them apart?  The answer is exactly the speed of light (not a coincidence).
Classically, two charges moving in the same direction will fly apart slower than normal because of their magnetic field. The protons in both wires see the electrons in both wires as denser due to length contraction.
So if magnetic fields are just weird relativistic effects, then where do magnetic poles, bar magnets, and whatnot come from? This perspective, that all magnetic dipoles (bar magnets, big and small) are reducible to current loops, helps explain a lot of things; like why there are no magnetic monopoles, and why atoms generate magnetic fields (an orbiting electron is essentially a current loop).
There are in these books beautifully clear explanations of the electrostatic force using simple Feynman diagrams (as you provide here), and general relativity using the example of a spinning disk, but no comparable explanation of f*cking magnets. The outline of the story goes something like a Feynman diagram for electrostatics with moving frames, but that hand-waving doesn’t get at the intuitive heart of why QED should imply basic magnetic properties like polarity, the right-hand-rule, and electron spin.
Indeed, the thing I have been looking for in over 20 years of libraries and archives, study books and writings of the best physicists was exactly this: please explain me the steps from QED applied to a bar magnet to the description of the magnetic field created by it. Suppose we create a magnet by using a soft-iron yoke in U shape with a coil wound around it at the middle (bend) part and the ends bend such that we get a nice homogeneous magnetic field between them. This description is a little abstract because you can never actually get a magnetic pole by itself.
Curio asked “why is there no magnetic force on a stationary charge next to a current carrying wire.” I think the electron would orientate itself in a particular direction due to its magnetic moment, but I do not think Faraday would agree with your comment “There is a small attractive force”, as an electric force is the result of a changing magnetic field, and for a stationary charge along side a wire with a steady current the magnetic field is constant. Although physicists can clearly predict magnetic effects; as people have commented above, physicists really do not understand magnetism. Of course a stationary charge placed beside a wire with no current, will feel a small attractive force, due to inducing an opposite charge on the wire.
What has a Physicist to say about the work done on a particle => Force ? the distance it moved in relation to a magnet? I have an even more difficult problem with the magnetic field (and electrostatic and gravitational fields as well).


I think that saying it’s just coulombs law and relativity is begging the question a bit.
The thing that got me for a while was why a charge moving next to a neutrally charged wire carrying current; why that charge curves.

Q: Are there examples of quantum mechanics that can be seen in every-day life, or do they only show up in the lab? Q: What kind of telescope would be needed to see a person on a planet in a different solar system? Q: Using modern technology, are we any closer to turning lead into gold than alchemists were hundreds of years ago? A classic example of one is the field created by an iron magnet; to see how the energy in such a field works, a small magnet can be placed under a piece of paper and iron filings sprinkled on it. Electrical currents are actually the force behind magnetic fields, which form as electrical charges move around. In navigation, ships can orient themselves with the assistance of the Earth's magnetic field, which is, incidentally, located several degrees off the geographic poles. In this case, the field is carefully generated and controlled by the operator of the machine for the purpose of gathering information about the human body.
An MRI machine, for example, can pull the keys out of an unwitting doctor's pocket, while a household magnet can be knocked from the refrigerator door with little effort.


If I walk toward this corner I feel like I am standing in front of a large TV set and getting the electricity off it.
Today, when I held a piece of food in front of the beak of my canary, I felt resistance in the air space about one inch between the food I held and his beak.
The magnetic north pole of the earth attracts the magnetic south pole of the compass needle.
Everything is in motion, its just that some motions appear static because they are repetitive or being looked at from a macroscopic viewpoint. Mathematically, the electric and magnetic fields can be derived from an electric potential field and a magnetic vector potential field, which can themselves be derived from a single scalar field. But, subtly, it’s not that that spin *generates* the magnetic field- that spin IS the magnetic field!!! As the filings respond to the magnetic field, they will slowly orient themselves along an axis. On a large scale like an electromagnet, the field is created by passing current through wires. In scientific research, these fields can be used to gather information about a location or object; geologists, for example, use tools called magnetometers to measure ambient magnetism to learn more about the underlying rock and mineral materials.
There are also many different types of magnetic fields; an iron magnet, for example, displays ferromagnetism, while those created with the use of an external current are known as electromagnetic fields. It was similar to the reverse magnetic field between two magnets but much weaker than the magnets.
I know the flow of electrons creates a magnetic field, but with a flow, interrupt that, and you have available energy. Larger examples include the Earth's magnetic field, and those that are created by other celestial bodies such as stars and planets. In the case of a household magnet, it is created by the movements of electrons in their orbits.
Scientists can also use other tools to create or alter magnetic fields for the purpose of learning more about the Earth. However, these meters have high fail rate for re-setting while a car is still parked there. It appears, though it is not entirely certain yet, that the Arhanov-Bohm effect is caused by the Magnetic Vector Potential outside of any measurable electric or magnetic fields.
I believe it is fairly likely that if we were to study the highest level of these fields, we would find other effects that are missing when looking solely at magnetic and electric fields. I have seen such a formulation where the wave forms of matter are distorted in ways that cause the effects of relativity.
Wave mechanics can also account for quantization and the indeterminancy of inter-related quantum measures, because the same thing is easily demonstrated to occur when measuring waves.
