Electromagnetic torques, precession and evolution of magnetic inclination of pulsars [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 We present analytic calculations of the electromagnetic torques acting on a magnetic neutron star rotating in vacuum, including near-zone torques associated with the inertia of dipole and quadrupole magnetic fields. We incorporate these torques into the rotational dynamics of a rigid-body neutron star, and show that the effects of the inertial torque ...

Electromagnetically Induced Torque on a Large Ring in the Microwave Range [PDF]
Physical Review Letters, 2014 We report on the exchange of orbital angular momentum between an electromagnetic wave and a 30 cm diameter ring. Using a turnstile antenna in the GHz range, we induce a torque on a suspended copper strip of the order of 10(-8) N m. Rotations of a few degrees and accelerations up to 4×10(-4) °/s2 are observed. A linear dependence of the acceleration as

Torque prediction using the flux-MMF diagram in AC, DC, and reluctance motors [PDF]
, 1996 This paper uses the flux-MMF diagram to compare and contrast the torque production mechanism in seven common types of electric motor. The flux-MMF diagram is a generalized version of the flux-linkage versus current (ψ-i) diagram for switched-reluctance ...
