Any movement of a conductor through this magnetic field does indeed produce a force on the electrons within it. But this force redistributes the electrons, generating another field that exactly ...

The break-even point here is expressed as having a Q (energy gain factor) of 1, where the added energy and losses within ... in a magnetic field as a self-stable compact toroid.

Highly charged heavy ions form a very suitable experimental field for investigating quantum electrodynamics (QED), the ...

Electric and magnetic fields are important factors to be considered when designing ... The conductors can be phased within a circuit so that the EMF emitted by each can partially cancel the others; or ...

Tiny magnetic "flowers" engineered by physicist Anna Palau are redefining how we manipulate magnetic fields. These ...

A flower-shaped structure only a few micrometers in size made of a nickel-iron alloy can concentrate and locally enhance ...

The new phase comes in the form of a pattern of electron spins—half of which are highly ordered, or "cold", and the rest of ...

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 ...

An open-transmit and 24-channel flexible receiver head coil enhances ultrahigh-field fMRI, enabling sub-millimeter resolution for somatosensory and motor cortex mapping, advancing neuroscience and ...
