Near Earth's magnetic poles, some of Earth's magnetic field - shown as red in this diagram - loops out into space and connects back to Earth. But some of Earth's polar magnetic field connects directly ...
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 ...

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 ...
Key learning points Properties of magnets What are magnetic fields? Magnetic fields lines are invisible but they fill the space around a magnet where the magnetic forces work on magnetic materials, ...
Littelfuse has created a three pin magnetic switch that draws only 200nA and operates at up to 50Hz. Called LF21112TMR, the detector uses a combination of TMR (tunnelling magneto-resistance) sensing ...
