having a curl, requires, according to Maxwell's theory, the explicit introduction of the macroscopic current. It cannot, of course, be described by a particular value of the magnetic permeability ...

Specific requirements of the application will also affect how magnetic shielding is chosen. Some common methods include using high-permeability alloys or coatings, creating a magnetic shield using a ...

Again, the cell can control which pumps are produced and under which circumstances. The combination of reduced entry and increased efflux is referred to as “reduced permeability” and is usually caused ...

Caledonia mining Corporation Plc (“Caledonia” or“the Company”) (NYSE AMERICAN: CMCL; AIM: CMCL; VFEX: CMCL) is pleased to ...

His design is conceptually similar to an induction cooktop, where alternating magnetic fields create eddy currents that heat metal cookware. But rather than using alternating currents through ...

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 ...

Wolf, E. 1955. Part III - Recent researches on the foundations of geometric optics and related investigations in electro-magnetic theory. IRE Transactions on Antennas and Propagation, Vol. 3, Issue. 4 ...

Magnetic field sensors are used to measure magnetic flux and/or the strength and direction of a magnetic field. They are used mainly in scientific measurement, navigation, and industrial applications.

Now researchers at Nanyang Technological University (NTU) in Singapore have found a way to heat up resins using an alternating magnetic field (PDF), so-called magnetocuring.

But while some falsies require messy glue, magnetic lashes make it easier than ever to amp up your fringe. Magnetic lashes take the mess out of the process and are less likely to come off ...
