Our physics expert picks his top-five equations, plus a scheme to supply US power needs with a bucket of baseballs. Thanks, ...

Some of the most sensitive methods of measuring magnetic fields use interactions of resonant ... is given by the product of three quantities in equation (1), the magnetic moment of the atoms ...

If these metals have not been turned into a permanent magnet they will still be attracted to a magnet if placed within a magnetic field. In this situation they act as a magnet - but only whilst in ...

Physics is a subject that demands regular and consistent practice. In order to master the concepts and formulas, students ...

When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet. The field inside a solenoid is strong and uniform. The small magnetic field caused by ...

The two groups 5,6 used very different approaches to eliminate the necessity for a strong magnetic field. Pribiag and colleagues 5 fabricated an STNO where one of the two magnetic layers was ...

The difference or "missing mass" is converted into energy in accordance with Einstein’s equation E=mc² ... main approaches for fusion energy research: Magnetic confinement fusion Magnetic confinement ...
