Scientists know well how conventional materials conduct heat. However, things are not as straightforward under extreme ...
With forefinger (magnetic field) pointing left to right, and second finger (current) pointing down, your left thumb (force) will point towards you. This is the direction in which the force acts.
The force is generated by a magnetic field gradient created by the magnets. The magnitude of the force (F) depends on the magnetic moment of the particle (m) and the gradient of the magnetic field (∇B ...
The ability to conduct heat is one of the most fundamental properties of matter, crucial for engineering applications. Scientists know well how conventional materials, such as metals and insulators, ...
