What is magnetic field strength? Electromagnetism: Electromagnetic forces are one of the four fundamental forces of nature. They play a very key role in shaping our environment because they underlie all chemical reactions because chemical reactions redistribute electrical charges. ...
What is magnetic field strength? How strong is a magnetic field? What are the main properties of the electric force defined by Coulomb's law? What creates an electric force field that moves electrons through a circuit? How does an electric field produce a magnetic field?
This shows the magnetic field strength around the two wires. Current is flowing into the wire on the right, and out of the wire on the left. Notice how the magnetic field is slightly stronger on the side of the wire facing the other wire? This is showing that the magnetic field around...
The force acting on an electrically charged particle in a magnetic field depends on the magnitude of the charge, the velocity of the particle, and the strength of the magnetic field. The Lorentz force has the peculiar property that it causes particles to move in right angles to their original...
The more common view of the magnetic field (among physicists) is that it is merely part of a larger structure called an “electromagnetic field”. Funny story: when Einstein first wrote his big-shit paper about relativity the whole “time and space” thing was more of a side note. What ...
the relation between magnetic field strength and magnetic influx is: H=B/μ−MH=B/μ−M. M is called magnetization. In case of magnetic bar, it exists only inside the bar. The relation is shown in this illustration: https://en.wikipedia.org/wiki/File:VFPt_magnets_BHM.svg It's sai...
I actually think one of the most common uses of magnets these days is to take money off people. There are all kinds of health claims about magnets that have never been proved, but people will spend a lot of money trying to reap the benefits from a magnetic force field or something. ...

The magnetic resonance imaging (MRI) physician's mantra has long been that MRI is without "side effects" and in particular without the terrible side scourge of computed tomo-graphic scanning: radiation. The lack of ionizing radiation with MRI is usually compelling compared to the known deoxyribonuc...
In addition to current traveling through a wire, magnetism is produced by the spin magnetic moments ofelementary particles, such as electrons. Thus, all matter is magnetic to some degree because electrons orbiting an atomic nucleus produce a magnetic field. In the presence of an electric field, ...
