Compasses were the trusted companions of sailors, explorers, and travelers for centuries, offering a simple way to find north ...

Figure 1 illustrates the pattern of magnetic fields emanating froma pair of vias carrying a purely differential signal. The figure looksdown on a multilayer PCB in plan view, showing the two ...

The sun is on the verge of a significant event: a magnetic field reversal. This phenomenon happens roughly every 11 years and marks an important stage in the solar cycle. The shift in polarity ...

Magnets are always fun when used in science experiments and demonstrations. They are fairly inexpensive to buy and can be ...
