... induced currents create a field that adds to that of the falling magnet. This is as if the additional field was created by yet another virtual magnet, this time with the same pole orientation. As a result, the force acting on the upper end is decelerating the fall, too. ...

Magnetic confinement of an electron beam
... 10 torr. The power supply is turned on and the voltage is increased till the discharge burns at high voltage (2-3 kV) and low current ~2-5 mA. If the discharge burns at lower voltages it is necessary to decrease the gas pressure until the required regime is obtained. Once the discharge is stable, th ...

Sheer Magnetism - Challenger Learning Center
... Individual atoms have been discovered to have magnetic fields. For this reason, the structure of the atom itself is closely linked to magnetism. Some atomic structures, however, like those that tend to form solids, such as the metals iron, cobalt, silver, gold, and copper, are more inclined to work ...

Weak magnetic field limit

CONTROL OF TRAVELLING WALLS IN A FERROMAGNETIC

Intuitively the system should not be controllable in θ, however this question is not very relevant from the physical point of view, since it is the position of the wall which is physically interesting. In particular, our result asserts that it ...

Magnetic monopole
A magnetic monopole is a hypothetical elementary particle in particle physics that is an isolated magnet with only one magnetic pole (a north pole without a south pole or vice versa). In more technical terms, a magnetic monopole would have a net ""magnetic charge"". Modern interest in the concept stems from particle theories, notably the grand unified and superstring theories, which predict their existence.Magnetism in bar magnets and electromagnets does not arise from magnetic monopoles. There is no conclusive experimental evidence that magnetic monopoles exist at all in our universe.Some condensed matter systems contain effective (non-isolated) magnetic monopole quasi-particles, or contain phenomena that are mathematically analogous to magnetic monopoles.
