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 ...

Figure 1: Schematic of device structures and current switching measurements of the devices. Figure 2: Electrical controllable deterministic magnetization switching by current pulses without magnetic ...

The Danish physicist Hans Christian Oersted was discussing in the year 1820 about the possibility of electricity and magnetism being associated to one another, and in the process presenting it finally ...

CBSE Science Class 10 Chapter 12 Mind Map: CBSE (the Central Board of Secondary Education) is the national educational board that has recently updated its syllabus. Following the changes in the ...

Magnetic skyrmions – quasiparticles with a vortex-like structure – show much promise as storage bits for next-generation computer memories and logic devices, but tracking their motion is no easy task.

In spaces smaller than a wavelength of light, electric currents jump from point to point and magnetic fields corkscrew through atomic lattices in ways that defy intuition. Scientists have only ever ...

A coil of wire, or solenoid, consists of a wire coiled up into a spiral shape. When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet. The field ...

(Reuters Health) - Electromagnetic fields produced by motors in electric cars don’t appear strong enough to interfere with implanted heart devices like pacemakers and defibrillators, a small German ...

There’s no escaping magnetic fields — they’re all around us. For starters, the Earth itself is like a giant magnet. A spinning ball of liquid iron in our planet’s core generates the vast magnetic ...
