The second problem is one in which the magnetic field is produced by current flowing in a pair of infinitely long parallel wires. When the line of supports of the elastic wire is parallel to these and equidistant from them we may apply the global bifurcation results of Crandall and Rabinowitz...
The strength of the magnetic field at the centre of an infinitely long cylindrical shell is affected by the current flowing through the shell and the distance from the centre of the shell. The strength decreases as the distance from the centre increases. ...
In terms of magneto- statics, the end of an ideal infinitely long and infinitesimally thin ferromagnetic wire, i.e. a Dirac string, behaves like a point monopole (probe nanowire shown in the upper part of Fig. 2a) and generates a radially symmetric magnetostatic stray-field. Thus, in our...
First, our procedure provides an answer to the long-standing question of what flux the SQUID actually couples to when λ is large. The necessary insight to answer this question then allows for a second important realization: that small filaments can be neglected in obtaining field solutions. Let...
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 ...
The invention pertains to advances in constructing predetermined magnets from appropriate magnetic material that allows for focusing the magnetic field in a target region.
The electric field E, which is added to the induced field, results from the potential difference between the electrodes. In the case of the AHMJET technology the potential difference is the surface area, A, times the axial length, Al, of the conductor magnetic plate, which defines the volume...
behaviours are quite reasonable because Maxwell’s equation outside the SC region could still be effectively approximated by a Laplace equation, and the infinitely large conductivity of a superconductor will take over the static Meissner effect to screen out the oscillating electromagnetic field. The...
The Stiffnessometer is based on the fact that outside an infinitely long coil, the magnetic field is zero while the vector potential A is finite. When such a coil is threaded through a superconducting ring, the vector potential leads to supercurrent density J according to the London equation ...
