magnetic field

Loggerhead turtles are equipped with two different abilities for sensing the Earth's magnetic field, yet scientists had not determined which one they rely on to interpret the magnetic map they inherit at birth.

The plasmasphere works with Earth's magnetic field to help block harmful charged particles from the Sun and deep space, offering natural protection for satellites and other technology.

However, they are not without limitations: they are sensitive to external disturbances -- such as strong magnetic fields near a hard drive -- and their performance typically degrades over time.

Just like moving fingers under the running water from a tap can disrupt its steady flow, HIP 67522 b disturbs the star’s magnetic field as it orbits around its host star.

This effect describes how the polarization of light rotates as it travels through a material placed in a constant magnetic field.
