themagnetic field at the centre of a circular coilappears to be straight line. The strength of the magnetic field decreases with an increase in distance from the loop. We have also discussed the factors affecting the magnetic field produced by a current carrying circular loop and some interesting...
The magnitude of the magnetic field equation is derived from Ampere-Maxwell law. The magnitude of the magnetic field is given by the formula: {eq}B=\frac {\mu _{0}*I}{2*\Pi *r} {/eq}, where r is the distance to the wire, I is the electric current, and {eq}\mu _{0} {...
From this point of view, the magnetic force F on the second particle is proportional to its charge q2, the magnitude of its velocity v2, the magnitude of the magnetic field B1 produced by the first moving charge, and the sine of the angle theta, θ, between the path of the second part...
The magnetic field created by one small current is weak. However, when the wire is wrapped around many times to form a coil, all the magnetic fields generated from each turn reinforce each other and result in a strong and nearly uniform magnetic field in the center of the coil. Such a ...
First-order magnetic processes (FOMPs), which can be due to a competition between crystal field contributions of different order from the free energy. It should be emphasized that there are no distinct boundaries between these FIPTs. Moreover, it is often possible to find some features inherent...
Magnetic dipole moments have dimensions of current times area or energy divided by magnetic flux density. In theSIsystem, the specific unit for dipole moment is thejoule(unit of energy) pertesla(unit ofmagnetic field strengthor magnetic flux density). In the centimetre–gram–second electromagnetic...
If the rotation axis of the gyroscope do not coincide with the angular momentum axis due to a “fast” external force, a superimposed precession around the angular-momentum and the gravity field axis occurs; the gyroscope nutates. In coexistence with damping, this nutation disappears on a short...
To calculate S in an isothermal process, one uses the formula. To calculate the magnetic entropy change, the entropy is first calculated with and without magnetic field. For an isothermal process, the quantity ΔS is given by40,56,63: [Math Processing Error]ΔS=S(B≠0,T)−S(B=0,T...
In an electrical machine, the magnetic losses or core losses are due to the soft magnetic material operating in a time-varying magnetic field. Core losses are made up of eddy current losses that arise from circulating electrical currents induced in conducting materials (the electrical steel used ...
Preferably, the movable magnetic field is generated by means of an inductor system which rotates with respect to the outer wall surface of the mandrel and which comprises either windings supplied with direct current, or permanent magnets.
