magnetic axis

magnetic axis

[mag′ned·ik ′ak·səs]
(electromagnetism)
A line through the center of a magnet such that the torque exerted on the magnet by a magnetic field in the direction of this line equals 0.
(plasma physics)
The single line of force that closes on itself after one revolution in a magnetic field with a rotational transform.

Unlike Jupiter and Earth's magnetic axis that are not aligned with its rotational axis, Saturn is different.
The shift confirmed with a compass does not confirm whether it was the earth's rotational axis or the magnetic axis. Or, maybe both axes shifted.
Saturn's magnetic axis aligns surprisingly well with its rotational axis.
A pulsar is a neutron star that spins rapidly and emits radio waves along its magnetic axis. If the pulsar's rotation emits a beam that reaches earth, it could technically emit several 'pulses' of energy in our direction at regular intervals, much like the recorded signal.
Consistent with previous observational studies of magnetic alignment in free-roaming vertebrates, first- and second-order analyses show that corvids exhibit robust axial alignment corresponding with the north-south magnetic axis. In contrast, when the data is pooled relative to the sun's azimuth, the first-order analysis is indistinguishable from random and the second-order statistics, although statistically significant, are a much weaker predictor of axial orientation compared to the distribution pooled relative to the magnetic field.
Magnetic axis without polarity was estimated via an indirect flux detection by online reactance measurement and the polarity was detected by finding minimum inductance on the estimated magnetic axis in [24].
The "pulses" of high-energy radiation we see from a pulsar are due to a misalignment of the neutron star's rotation axis and its magnetic axis.
The researchers suspect that the unfamiliar appearance of the newly observed auroras is due to Uranus' rotational weirdness and peculiar traits of its magnetic axis. The magnetic axis is both offset from the center of the planet and lists at an angle of 60 degrees from the rotational axis -- an extreme tilt compared to the 11 degree difference on Earth.
Hard disks store data by magnetizing small domains of a disk's surface so that the magnetic axis points in one of two opposing directions.
The preferred magnetic axis (M) also can often be determined from the relative intensities.
For reasons that are not yet understood, Neptune's magnetic axis is steeply tilted (about 50[degrees]) in relation to its rotational axis.
