Magnetic effect of electric current is one of the major effects which functions as the basic principle in appliances used in various fields of activities. The magnetic field around a current carrying ...

Using nanoparticles and alternating magnetic fields, scientists have found that head and neck cancerous tumor cells in mice can be killed in half an hour without harming healthy cells. The findings ...

This video explains the function of inductors and how they store energy in a magnetic field when current flows through them. Inductors are essential passive components used to manage current changes ...

(Nanowerk News) The quantum Hall effect, a fundamental effect in quantum mechanics, not only generates an electric but also a magnetic current. It arises from the motion of electrons on an orbit ...

Since the early pioneering work of Debye, Hückel, Bjerrum and Onsager on model electrolytes, the physics of Coulombic systems has been elucidated in many contexts, from electrolytes to dusty plasmas 1 ...

Electromagnetic fields as they would be generated by positive and negative electric charges, both at rest and in motion (top), as well as those that would theoretically be created by magnetic ...

Allegro MicroSystems has announced a 4 x 4mm QFN current sensor that measures hundreds of amps bidirectionally, with a burden resistance of ~100μΩ (plus ~500pH). Called ACS37220, five versions are ...

Such behaviour would have quite curious effects for a light switch: In the case of a lamp dimmer switch, the correlation, which the physicists at the Max Planck Institute of Microstructure Physics in ...

Allegro's ACS37030 50-A current sensor protects wide-bandgap GaN devices by sensing current over the industry’s widest frequency range for automotive, industrial, and consumer applications. Featuring ...

Melexis has announced a magnetism-based current sensor that needs no ferromagnetic core, for measuring currents through power PCBs and busbars (see diagram). MLX91235 is gradiometric, taking a ...
