Magnetic field

In physics, a magnetic field is that part of the electromagnetic field that exerts a force on a moving charge.

A magnetic field can be caused either by another moving charge (i.e., by an electric current) or by a changing electric field.

Water Birds Reveal New Direction for Aircraft Landing Research

Water Birds Reveal New Direction for Aircraft Landing Research

Reuters (Aug. 8, 2013) Research into the landing behavior of water birds has revealed that they appear to align with magnetic field lines to choose their preferred landing direction, which is usually along the north-south axis. Czech scientists say the research could assist in improving landing navigation systems for aircraft, helping to prevent accidents when planes land close to water.

Quantum Levitation: When Science Imitates Magic

Quantum Levitation: When Science Imitates Magic

FORA.tv (Nov. 16, 2012) In Oct 2011, Boaz Almog and Barak Deutscher from the superconductivity group at Tel-Aviv University lead by Prof. Guy Deutscher, demonstrated how a superconductor disk is trapped in a surrounding magnetic field, a phenomenon called "Quantum Levitation" or "Quantum Locking". By using the exceptional large scale superconductors produced by Mishael Azoulay, they are able to demonstrate a quantum effect that, although well known to physicists worldwide, was never seen and demonstrated this way. In addition to developing new superconductor technologies and applications, the superconductivity group in Tel-Aviv University is dedicated to teaching and educating the young and adults about superconductivity, through the unique and counter-intuitive phenomena of 'quantum locking' and 'quantum levitation'.

Wearable Technology Will See Growth in the Medical Field

Wearable Technology Will See Growth in the Medical Field

TheStreet (Mar. 18, 2014) The top venture capitalists at the digital SXSW conference in Austin, Texas believe wearable technology will see most of its growth in the medical field. While fitness wearables have taken off and thousands have been sold, the medical field has the promise for the most innovation. Investors talked excitedly about devices that warned of impending seizures or technology that measures brain trauma -- even a product that monitors an aging parent has great potential.
