... It is conventional to define two more vector fields, the magnetic field H and the magnetization M, as follows: • μ0H is the magnetic field in vacuum due to currents. • μ0M is the magnetic field generated by a diamagnetic or paramagnetic material. We have defined the magnetic susceptibility by μ0M = ...

... • The reconnection of open field lines also forms closed field lines earthward of the X-line. • Eventually the balance of forces in the plasma sheet changes and the X-line begins to move tailward. • Earthward of the X-line the plasma sheet thickens and strong earthward flows are observed. • As the ...

... An electromagnet consists of a coil of wire usually wound around an iron core. The core becomes magnetized when an electric current is sent through the wire coiled around it. Electromagnets have many essential applications, including picking up metal containing iron in salvage yards, use in speakers ...

Activity Lesson Plan
... Go over the results of the magnetism test. Were there any materials that fooled the students? What do all the magnetic objects have in common? (They are made of metals that contain iron.) 5. (10 minutes) Will magnetic force go through matter and/or air? How can we test this? Define permeable ...
