A system of a finite number of harmonically-trapped fermions in one dimension, in the presence of a static magnetic field, is studied within the framework ... HA Al-Khzon,HB Ghassib,MK Al-Sugheir - 《Revue Canadienne De Physique》 被引量: 0发表: 2015年 ...
Permeance coefficient Pc is used to express the operating point of the magnet on the B-H curve. This value is defined as the ratio of magnetic flux density Bd and magnetic field strength Hd at the operating point and expressed by the following formula (see the figure above): 1-4-a. Per...
PROBLEM TO BE SOLVED: To improve operability between an element and external magnetic field by making a resistance changing rate represented by a specific formula to be negative when a specified external magnetic field is applied, and constituting the element in a manner that the absolute value of...
The magnetic dipole moment has the dimension of Acurrent x length Bcharge x time x length Ccurrent x area DcurrentareaSubmit The magnetic field to a small magnetic dipole of magnetic moment M, at distance r from the centre on the equatorial line is given by (in M.K.S. system) Aμ...
is due only to induction by the variable magnetic field, and the order of magnitude of E inside the body can be obtained by estimating the terms in the equation curl E = − (1/c)∂B/∂t, whence E/l ∼ ωH/c or E ∼ (ωl/c)H, where l is the dimension of the body...

III. Atoms in homogeneous magnetic field We prove a large number of results about atoms in constant magnetic field including (i) Asymptotic formula for the ground state energy of Hydrogen in large field, (ii) Proof that the ground state of Hydrogen in an arbitrary constant fiel... JE Avron...
As the magnetic field scales with the geometry of the bearing, the absolute lift of the bearing will increase as the size of the bearing is increased. However, the relative stiffness, which is the gradient of the force with respect to the size of the bearing remains constant. This argument...
the magnetic field, and (iii) the lattice minimizing the energy of the latter solutions per unit volume approaches the hexagonal one as the magnetic field strength approaches the threshold. We expect that these solutions are stable under field fluctuations and, in fact, minimize the energy locally...
