Since the magnetic field lines in the north and south lobes are in opposite directions, the plasma sheet currents are duskward. In the distant plasma sheet, the lobe magnetic pressure and the plasma pressure ...

The Power of Magnets
... Suggested interpretation of the proverb In life when you work as a team it is usually more effective than working on your own. In this activity students will learn about the power of magnets, including the way magnets (usually weak) and electromagnets can combine to make powerful and useful machiner ...
