Maglev propulsion and levitation may involve the use of superconducting materials, electromagnets, diamagnets, and rare-earth magnets. As an alternative to high-speed rail based on traditional flanged-wheel vehicles, the technology of magnetic… How is electricity used in a maglev train? In EDS systems, magnets on the train induce currents in theRead More →
A magnetic north pole attracts a magnetic south pole, but repels another north pole. … Even at the atomic level, north and south poles always appear together. One cannot produce in this way a solitary pole, or monopole, that acts as a single point source of the magnetic field. WhichRead More →
All of the loops of wire which make up a toroid contribute magnetic field in the same direction inside the toroid. The sense of the magnetic field is that given by the right hand rule, and a more detailed visualization of the field of each loop can be obtained byRead More →
Yes, magnets can be used to corrupt data on a hard drive – in theory. Bringing a powerful magnet into contact with the magnetic platters could corrupt them and render the data stored on the platters unusable. What can damage a SSD? It can be caused by a variety ofRead More →
