Magnetic field line - Simple English Wikipedia, the free ...

2022-1-1 · A magnetic field line or magnetic flux line shows the direction of a magnet's force and the strength of a magnet.. The idea of lines of force was invented by Michael Faraday.His theory is that all of reality is made up of force itself. His theory predicts that electricity, light, and gravity have finite propagation delays. Einstein's theory agrees with this.

Magnetic field | Article about magnetic field by The Free ...

a force field that acts on moving electric charges and on bodies that have a magnetic moment, regardless of the state of their motion. A magnetic field is characterized by the vector of magnetic induction B, which defines the force acting on a moving electric charge at a given point in the field, the action of a magnetic field on bodies that have a magnetic moment, and also other

2018-5-14 · Magnetic field. Earth acts as though it were a huge dipole magnet with the positive and negative poles near the North and South Poles. This does not mean that Earth is literally a dipole magnet — there are too many variations in the field — but that the best fit for a model of the field is two poles of a magnet, rather than a quadrupole, or other shape.
