Explore the fascinating comparison between magnetic fields produced by a current loop and electric fields generated by a dipole. This short breaks down key similarities and differences using clear ...

Explore two effective methods for finding the magnetic field of a current-carrying wire loop. This short explains the reasoning behind each approach and shows how they connect theory with practical ...

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 ...

Performance-driven measurement instrumentation requires low-noise, high-bandwidth linear front-end circuits that combine with equally well-performing A/D converters and clocking (Figure 1). Designers ...

Allegro has added magneto-resistive sensors to its Hall-based range of current and magnetic field devices, for high-sensitivity high-bandwidth applications. The first product is a 5A 1MHz isolated ...

PC-board layout sets the functional, electromagnetic interference (EMI), and thermal behavior of a power supply. Good layout from first prototyping on actually saves significant resources in EMI ...

Magnetic illusion: a long wire surrounded by a magnetic replicator generates a replica of the wire outside it. (Courtesy: Phys. Rev. Lett. 10.1103/PhysRevLett.125.177204) Physicists in the UK and ...

It is not known when humans first noticed the attraction or repulsion between pieces of magnetic material. The first important device depending on these forces was the magnetic compass, which is ...
