... There is a big complication in measuring the EMF generated by the moving rod: The wires that connect the meter to the rod also move through the magnetic field, and therefore, there is an electromotive force for them also. This is a general problem: A voltmeter can measure the EMF produced only in a ...

Circular Motion
... Gravitational force is the mutual force of attraction between particles of matter. Orbiting objects are in free fall- Newton observed that if an object were projected at just the right speed, the object would fall down toward Earth in just the same way that Earth curved out from under it. So, it wou ...

Spin-current-induced electric field
... spin-down electrons are the same, and both kinds of electrons move in the same direction under an external electric field. The total spin-current I s ⫽ (I ↑ ⫺I ↓ ) is therefore zero, and only the charge current I ec ⫽e(I ↑ ⫹I ↓ ) is relevant. When a system includes ferromagnetic materials, or unde ...
