There's a magnet in a secure room in central Tokyo. It's an electromagnet, the kind that generates a magnetic field when ...

Today, manufacturing strong magnets is no problem from a technical perspective. It is, however, difficult to produce a permanent magnet with a magnetic field of a specific pre-determined shape.

GRENOBLE, France--(BUSINESS WIRE)--Hprobe, a provider of semiconductor Automatic Test Equipment (ATE) for magnetic devices, today announced the completion of a new funding round driven by ...

A permanent magnet is always magnetic. It has an invisible magnetic field. Only certain materials, such as iron, feel a magnetic force. Permanent magnets can come in lots of different shapes and ...

The 0.7 Tesla magnet, developed by Federico Casanova and his colleagues at the RWTH Aachen University’s department of macromolecular chemistry, is about the size of a standard D battery and weighs 500 ...

In medicine permanent magnets demonstrate unique advantages in terms of field strength, tunability of field and gradient distributions, and practical implementation. The findings highlight the ...

In this situation they act as a magnet - but only whilst in the magnetic field. This is called induced magnetism. Substances that can be permanently magnetised are described as magnetically hard.

CAMBRIDGE, Mass-- A major limitation in the performance of solar cells happens within the photovoltaic material itself: When photons strike the molecules of a solar cell, they transfer their ...

Using this method, [efeyenice983] found that the Earth’s magnetic field strength at their location was about 0.49 Gauss, which is well within 0.25 to 0.65 Gauss that is typically found on the ...

Magnetic effect without a magnet Date: February 22, 2021 Source: Vienna University of Technology Summary: Electric current is deflected by a magnetic field -- this leads to the so-called Hall ...
