Piling and avalanches of magnetized particles [PDF]

Physical review. E, Statistical, nonlinear, and soft matter physics, 2004
We performed computer simulations based on a two-dimensional Distinct Element Method to study granular systems of magnetized spherical particles. We measured the angle of repose and the surface roughness of particle piles, and we studied the effect of ...

Circular orbits and collisions of particles with magnetic dipole moment around magnetized Bocharova–Bronnikov–Melnikov–Bekenstein black holes

European Physical Journal C: Particles and Fields
In this study, we investigate the motion of magnetized particles around a Bocharova–Bronnikov–Melnikov–Bekenstein (BBMB) black hole in an external magnetic field, emphasizing the effects of an external magnetic field and a conformally coupled scalar ...

Magnetized Cell‐Scaffold Constructs for Bone Tissue Engineering: Advances in Fabrication and Magnetic Stimulation [PDF]

Advanced Science
Magnetic particles (MPs), due to their unique physical and chemical properties, have emerged as promising tools in bone tissue engineering. Their incorporation into scaffolds or uptake by bone cells, combined with exposure to external magnetic fields ...

Dynamic magnetic fields transform pivoting H2SiO3 particles to hollow microspheres with nanofibrous interior [PDF]

Nature Communications
Reorganizing the internal structures of hollow microspheres after shell sealing, without damaging the shell, remains a major challenge. Here, we show a dynamic magnetic field fluxes stirring (DMFFS) technology that can transform H2SiO3 particle to a ...

QPOs from charged particles around magnetized black holes in braneworlds

European Physical Journal C: Particles and Fields
Quasiperiodic oscillations (QPOs) are a powerful tool for testing gravity theories, probing gravitational and electromagnetic field properties, and obtaining constraints on the black hole and field parameters.

Circular motion and collisions of particles with magnetic dipole moment and electric charge in dipolar magnetosphere around Schwarzschild black holes

European Physical Journal C: Particles and Fields
No-hair theorem indicates that black holes cannot have their own magnetic dipole moment. They can be weakly magnetized in binary systems with a neutron star companion and an accretion disc of charged particles.

Spinning magnetized particles orbiting magnetized Schwarzschild black holes [PDF]

Physical Review D, 2023
A way to test electromagnetic field and spacetime properties around black holes is by considering the dynamics of test particles. In fact, in real astrophysical scenarios, it is hard to determine spacetime geometry which is dominating due to degeneracy ...
