ACOUSTIC TRACTOR BEAMS have been the invention of imaginative SciFi writers. But since 2012, equally imaginative science has made advances in this subject. Once again, at the heart of this is the subject of waves, and their bendiness. View in LinkedIn

BIG NANO FORCES. "The usually attractive vacuum forces, the Casimir and the related van-der-Waals force, are significant on the length scale of nanomachines; so ideas for manipulating vacuum forces may find applications in nanotechnology." https://lnkd.in/eCBg2Ha View in LinkedIn

FRICTION-FREE. "Another useful application is the creation of truly frictionless bearings. The bearing would be able to rotate, but it would be suspended without direct physical contact with the surrounding housing, so that there wouldn't be any friction." https://lnkd.in/emW6Tsg View in LinkedIn

QUANTUM LEVITATION. "Left-handed metamaterials are known to make perfect lenses that image classical electromagnetic fields with higher resolution than the diffraction limit. For optical left-handed metamaterials, this repulsive force of the quantum vacuum may levitate ultra-thin mirrors on, literally, nothing." https://lnkd.in/eCBg2Ha View in LinkedIn

MAGLEV TRAINS. "There are already magnetic levitation trains in Asia which use this process, in addition to the more traditional electromagnetic levitation (maglev) trains." https://lnkd.in/emW6Tsg View in LinkedIn

MAGLEV CARS. "Unfortunately, the current intensity of this effect is such that we won't have flying cars for quite some time. Also, it only works over a strong magnetic field, meaning that we'd need to build new magnetic track roads." https://lnkd.in/emW6Tsg View in LinkedIn

WIDESPREAD PHENOMENON. "If you measure very carefully, however, you find that there are small magnetic forces between magnets and 'non-magnetic' materials like pieces of copper or pieces of wood or people. Some of those 'non-magnetic' things are attracted to magnets and others are repelled." https://lnkd.in/evABxQC View in LinkedIn

PERMANENT MAGNETS. "In some materials, the electrons can lower their energy by lining up magnetically into magnetic domains. In each domain, most of the electrons pull and push together, so you can get big forces. In some materials (permanent magnets) the domains can all be lined up so you get really big magnetic forces." https://lnkd.in/evABxQC View in LinkedIn

"MAGNETISM can either pull the two objects together or push them apart, depending on which way the magnets point. Most importantly, it depends on what is going on with the electrons in the material, since each electron is like a tiny magnet itself. Most materials feel very little magnetic force because their electrons act like magnets that are pointing every which way, more or less equal numbers pulling or pushing." https://lnkd.in/evABxQC View in LinkedIn
