... When two coils are placed near each other, alternating current in one (the primary, which is the one connected to the power source) induces a changing magnetic field. The second coil is within that field, so it has a current induced in it. If the first coil has fewer loops than the second, the secon ...

... Why is the aurora borealis visible from some parts of the world and not others? We’ve learned that an aurora borealis occurs when particles from the sun’s solar winds hits the Earth’s atmosphere at an angle and this can only happen at the poles of the Earth. Just like a small magnet, the Earth’s mag ...

Using Superconductivity to “See” a Spin Axis
... spacetime twists slightly (see “FrameDragging” card). The predicted amount of turn is extremely small (< 0.002% of a degree), which means that the gyroscope must be extremely stable while it is spinning (~10 -12 degrees of drift per hour). Given this need for an ultra-stable spin, how could GP-B mea ...

... You may see a small reading from the probe even when it is not next to a magnetic field. This is due both to local conditions and variations between data loggers. It is quite usual and can normally be ignored where trends of change and field strength are generally more important than accuracy. Some so ...
