Torque Experienced by a Current Loop in a Uniform Magnetic Field. We know that the current loop when placed inside the magnetic field, it behaves like a magnetic dipole where it has a North and the South pole. So, magnetic moment, M = IA. Now, consider a rectangular loop placed inside the magnetic field. (image will be uploaded soon)
0 includes the external and internal magnetic eld, H s is the surface anisotropy eld, A ex is the exchange constant, h(r;t) is the dipolar magnetic eld due to m(r;t), is the Gilbert damping constant, ˝ STT is the spin-transfer torque due to the spin current injection from the top surface and ˝ SP is the spin pumping torque due to the ...
Solution. (a) If the magnetic force is the only one of significance acting in this problem, then F=ma=evBsinθ. Thus, v =ma=eBsinθ = (9.11 ×10. −31kg)(6 ×1015m/s2)=(1.6 × 10−19C)(0.1 T)sin90° = 3.42 × 105m/s.
Using anisotropic London theory the intrinsic magnetic torque for extreme type 2 uniaxial superconductors for any value of the magnetic induction is obtained. It considered the vortex lines straight and takes into account the contribution of the supercurrents flowing inside the vortex core within the London theory. It is shown that the interline and intra line free energies give opposite ...
Then, using the magneto-mechanical ratio J = γP and substituting the magnetic torque L = Equation 5.2 obtains the form: (5.3) By dividing Equation 5.3 by magnetic constant μ 0 the equation is converted to the version of the Landau-Lifshitz equation for undamped rotation of the magnetization (Figure 5.1a ):
