Statement – 2: In an A.C. Generator, as the armature is rotated in a uniform magnetic field, the magnetic flux linked with ...

Optimum coil currents, coil radii, and coil distance are designed to provide with zero magnetic field at zero range and maximum magnetic field at a focal range. This DMF performance is found to be ...

In this study, we propose an analytical model to account for the eddy current effect on the performance of the LHG. Initially, the harmonic field distribution of the levitation coils is deduced by ...

Controlling magnetism in a device is not easy; unusually large magnetic fields or lots of electricity are needed, which are ...

A flower-shaped structure only a few micrometres in size made of a nickel-iron alloy can concentrate and locally enhance magnetic fields. (Nanowerk News) A flower-shaped structure only a few ...

However, things are not as straightforward under extreme conditions such as temperatures close to absolute zero combined with strong magnetic fields, where strange quantum effects begin to dominate.

One way to get moving charges is to run electric current through a wire. (This is literally a stream of electrons.) This will create a magnetic field, and other wires with electric current will ...

Specifically, the researchers traversed a prominent type of current in the Mozambique Channel known as an eddy-ring dipole. In an eddy-ring dipole, an anticyclonic ring—in which water swirls ...

Flower-shaped magnetic metamaterials are being used to boost the power of magnetic sensors and imaging tools by focusing magnetic fields with pinpoint precision. Credit: SciTechDaily.com Tiny magnetic ...
