NASA has been monitoring a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies ...

Earth's magnetic field acts like a protective shield around the planet, repelling and trapping charged particles from the Sun ...

And no matter what the condition of the board is, once you’ve plugged in more than a few components, the circuit becomes hard to follow, much less troubleshoot when things go pear-shaped.

This means that the current to the external circuit is always in the same direction. increasing the rate of rotation increasing the strength of the magnetic field increasing the number of turns on ...
