... The factor “i” (j is also used) in the table above means “out of phase by a quarter-cycle in reference to voltage applied”. When an impedance is purely capacitive, current leads voltage by a quarter cycle; when an impedance is purely inductive, current lags voltage by a quarter cycle (following figu ...

The observer may call this the boundary layer, and the region beyond the free-stream or the mainstream, and he may feel that the interface between the two is reasonably sharp, so that he can call it the edge of the boundary layer. The theoretician will see no such sharp interface but will employ a m ...

DYNAMO THEORY Chris A. Jones
... If there is no fluid motion to maintain the dynamo, the field diffuses away. More precisely, if there is no field at infinity it diffuses away to zero, but if a conductor is immersed in a uniform field, the field inside the conductor eventually becomes uniform. How long does this diffusion process t ...

Simulation of Charged Particle Orbits in Fusion
... Time-varying fields will not be considered. This is because in real tokamaks the confining magnetic field varies slowly enough to be considered constant for our application. There are fluctuating fields as well due to turbulence and instabilities, but that is also outside the scope of the thesis. In ...

Electromagnet
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off. Electromagnets usually consist of a large number of closely spaced turns of wire that create the magnetic field. The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagnetic material such as iron; the magnetic core concentrates the magnetic flux and makes a more powerful magnet.The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the winding. However, unlike a permanent magnet that needs no power, an electromagnet requires a continuous supply of current to maintain the magnetic field.Electromagnets are widely used as components of other electrical devices, such as motors, generators, relays, loudspeakers, hard disks, MRI machines, scientific instruments, and magnetic separation equipment. Electromagnets are also employed in industry for picking up and moving heavy iron objects such as scrap iron and steel.
