Maybe you're concerned about the long-term impact of having all your atoms mixed about, but once you're out of the magnetic field, your body and its chemistry return to normal. There are no known biological hazards to humans from being exposed to magnetic fields of the strength used in ...
ofFieldIn nature, there are two fundamentally different types of motion of the electric and magnetic fields: dynamic and kinematic. A typical manifestation of the first type of motion takes place in a plane harmonic EM-wave. For already more than a century the question about the ratio of the...
Magnetic and electrical fields are related, and magnetism, along with gravity and strong and weak atomic forces, is one of the four fundamental forces in the universe. But none of those facts answers the most basic question: What exactly makes a magnet stick to certain metals? Or why don't...
Once the train is levitated, power is supplied to the coils within the guideway walls to create a unique system of magnetic fields that pull and push the train along the guideway. The electric current supplied to the coils in the guideway walls is constantly alternating to change the polarity...
Ohm's law and resistance resistivity and how it affects the resistance of a material fuses and how they protect wiring and appliances how electricity is produced devices used to measure voltage, current and resistance the effects of electric and magnetic fields conductors, insulators and superconductor...
A volt-ampere specification is also useful to measure reactive power, which is the power needed in capacitors and inductors to create electric and magnetic fields. It is measured in volt-ampere reactive and is required for power transmission lines. ...
Numerous earlier patents cover his various improvements to electron tubes and his systems for deflecting cathode rays and deflecting electron beams with electric and magnetic fields. US Patent 3,191,028: Electron scanning microscope by Manfred Von Ardenne and Bodo von Borries, patented May 13, 1941...
Magnets are a direct result of the physics taking place at the atomic level (i.e. quantum level) within the material of the magnet. Magnetic fields are polarized with two magnetic poles called North and South. One of the interesting features of a magnet is that, if you break it into ...
These electric and magnetic fields (electromagnetic fields) induce each other in space at the speed of light, traveling outward away from the antenna. Analog vs. Digital Radio Although analog radio sources are still pervasive, digital signals like Wi-Fi and Bluetooth have taken over. In 2009,...
Magnetic fields are produced by the motion of electrical charges around an electrified wire. How is a magnetic field created? When current flows in a wire, a magnetic field is created around the wire. From this it has been inferred that magnetic fields are produced by the motion of electrica...
