Maxwell's Fourth Equation expresses the observation that a continuous electrical current I or a displacement current (∂D/∂t) gives rise to a magnetic field. At a distance r from a wire with direct current I, for example, the magnetic field is given by (4.20G)H=2Icr (4.20S)H=I2...
When the angle is zero degrees then both B and V are on the same plane and sin 0=0 leading to no magnetic force. So, when the charge is moving with a velocity V parallel to the magnetic field B, it will not be under the effect of a magnetic force F=0. For a magnetic force ...
The asymptotic solution of the Schrodinger equation with non-separable variables is obtained for a particle confined to an infinite elliptic cylinder potential well under applied uniform longitudinal magnetic field. Using standard-problem method, dimension quantized eigenvalues have been calculated when the ...
The Bio-Savart law is an expression that is used to find the magnetic field strength and direction at any point in space. It is a multivariable vector integral that can be simplified into a simple algebraic expression for an infinite, current-carrying wire. What is Biot-Savart law derivation...
Consider a straight wire that carries a steady current I. Experiments (in the 19th Century) revealed that the current flow generates a magnetic field that is perpendicular to the direction of the wire and that the lines of magnetic force are circular, with the line integral ∮B·dr around a...
When there are frequent collisions, the particle comes to a limiting velocity proportional to E. The electrons in a copper wire, for instance, drift together with a velocity \rm v=\mu E , where \mu is the mobility. A magnetic field also limits free-streaming by forcing particles to ...

The nucleus of the high-voltage system is the magnetron tube.The magnetron is a diode-type electron tube which is used to produce the required 2450 MHz of microwave energy.It is classed as a diode because it has no grid as does an ordinary electron tube.A magnetic field imposed on the ...
First, the model of antenna feeds has a direct impact on input impedance calculation. Wire antennas are usually driven by coaxial cables. Using the equivalence principle, coaxial feeds can be considered as magnetic frill sources radiating in free space. Although the delta-gap source model is ...
