Magnetars are neutron stars characterized by some of the most powerful magnetic fields in the Universe, as well as their intense X-ray and gamma-ray emissions and outbursts. An international team ...
As with all currents, the induced current creates a magnetic field around itself. Note that this magnetic field opposes the original change. For example, if a magnet is moved into a coil of wire ...
American researchers have measured a tiny electrical voltage by exploiting Earth's magnetic field in the planet's rotational motion. This discovery, though modest, revives a scientific debate ...

How a tokamak works: The electric field induced by a transformer drives a current (big red arrows) through the plasma column. This generates a poloidal magnetic field that bends the plasma current ...
