Turbulent Dynamo in Asymptotic Giant Branch Stars [PDF]
, 2001 Using recent results on the operation of turbulent dynamos, we show that a turbulent dynamo can amplify a large scale magnetic field in the envelopes of asymptotic giant branch (AGB) stars.

Magnetic Losses in Soft Ferrites
Magnetochemistry, 2022 We review the basic phenomenology of magnetic losses from DC to 1 GHz in commercial and laboratory-prepared soft ferrites considering recent concepts regarding their physical interpretation. This is based, on the one hand, on the identification of the contributions to the magnetization process provided by spin rotations and domain walls and, on the ...

Synchrotron radiation by fast fermions in heavy-ion collisions [PDF]
, 2010 We study the synchrotron radiation of gluons by fast quarks in strong magnetic field produced by colliding relativistic heavy-ions. We argue that due to high electric conductivity of plasma, time variation of the magnetic field is slow and estimate its ...

Effect of Magnetic Properties of Magnetic Composite Tapes on Motor Losses
Energies, 2022 Alternating current (AC) copper losses in motors increase with carrier frequency of the pulse width modulation (PWM) and are further increased by leakage flux of the permanent magnet. Therefore, AC copper losses increase with motor speed.

Magnetic Field Dependent Microwave Losses in Superconducting Niobium Microstrip Resonators
, 2018 We describe an experimental protocol to characterize magnetic field dependent microwave losses in superconducting niobium microstrip resonators. Our approach provides a unified view that covers two well-known magnetic field dependent loss mechanisms ...

Magnetically controlled mass loss from extrasolar planets in close orbits [PDF]
, 2014 We consider the role magnetic fields play in guiding and controlling mass-loss via evaporative outflows from exoplanets that experience UV irradiation. First we present analytic results that account for planetary and stellar magnetic fields, along with ...
