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 close magnetAn object that produces a magnetic field which pulls on other magnetic materials and attracts or repels other objects. create magnetic fields. These magnetic fields cannot be seen.

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 ...

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 poles of the sun’s magnetic field are fading away. But don’t panic: it’s all part of our host star’s usual 11-year cycle of activity. Over the past couple of years, solar activity—as measured by ...

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, ...
