We here present a novel deep learning (DL) approach for designing structures of permanent magnets. The challenge for the DL method in this kind of problem is to learn the mapping from a desired magnetic field to a simple magnetic structure, i.e., an inverse design approach. We demonstrate this approach by training six different standard convolutional neural network (CNN) …
Transcranial magnetic stimulation (TMS) is a noninvasive form of brain stimulation in which a changing magnetic field is used to cause electric current at a specific area of the brain through electromagnetic induction.An electric pulse generator, or stimulator, is connected to a magnetic coil, which in turn is connected to the scalp.The stimulator generates a changing electric current within ...
A 1-tonne deep field magnet typically has a 60mm deep field, so on 20mm material thickness, it is rated to lift 350kg which is the same as a PML 500kg magnet. A shallow field magnet rated to lift 400kg has a 12.7mm deep field so it can lift 400kg of 12.7mm material. When you are handling 20mm plate it is still rated to lift 400kg. Interestingly ...
Deep transcranial magnetic stimulation, also known as Deep TMS, is a non-drug, non-invasive yet effective treatment for depression patients.It is a type of brain stimulation technique where pulsed magnetic fields are generated by a coil placed on the scalp. This current essentially activates the neuronal circuits at the stimulation site, resulting in symptom improvement.
Magnetic shielding consists of forming a large magnetic field around the spacecraft, usually through the use of superconducting solenoids.

The extremely sensitive Chandra Deep Field-North (CDF-N) pencil-beam X-ray survey is used to identify and characterize the X-ray emission from old high-latitude main-sequence Galactic stars. Our principal goal is to investigate the expected long-term decay of magnetic activity of late-type stars due to the gradual spin-down of stellar rotation from a magnetized stellar wind.

magnetic field creates bound currents on the surface of a magnetic material. Just like the D-field has a Gauss's law that only depends on free charges, the H-field has an Ampere's law that is only sensitive to free currents. We next discuss the boundary conditions that apply on the surface of a magnetic …
Saturn's magnetic field is created as material cycles deep within the planet's fluid interior. Outside Saturn's magnetosphere, a million-mile-per-hour flow of electrically charged particles (electrons and ions) from the sun, called the solar wind, spreads out through the solar system. When the solar wind encounters Saturn's own magnetic field ...

Charged Particles Spiral Along Earth's Magnetic Field Lines: Energetic electrons and protons, components of cosmic rays, from the Sun and deep outer space often follow the Earth's magnetic field lines rather than cross them. (Recall that the Earth's north magnetic pole is really a south pole in terms of a bar magnet.
The magnetic field strength is a measurement of the magnetic field's strength and direction at a particular point near the magnet. It is expressed in Gauss or Tesla (1 Tesla = 10,000 Gauss). It depends on the size, shape and grade of the magnet, where the measurement is performed, and the presence of any other magnets or ferromagnetic materials nearby.
