Concerning long-term geomagnetic variations and space climatology
... much during a polarity transition, an assumption valid only if the magnetospheric magnetic field is still dominated by a magnetic dipole aligned with the rotation axis. If quadrupole or octupole contributions from the internal field become important or even dominate the field or if the orientation o ...

DISCOVERING AND ANALYZING MAGNETIC FIELDS
... calculations were not exact because the current output was different depending on the age of the battery; however, they provided a good approximation. With the nail inside, the solenoid became an iron core solenoid and the permeability constant changed to the permeability of iron given in Equation 3 ...

... mathematical relationships can be used to describe the nature of such a field? This will lead us to present Ampère's law, which describes the magnetic field around a closed loop as a function of the current enclosed by the loop. (2) We will explore Faraday's law, which describes how changing magneti ...
