Magnetic measurement is an old science, but it's one that continues to be of tremendous importance. The compass is a familiar magnetometer that indicates the horizontal component of the ambient magnetic-field vector. Magnetic measurements today are accomplished by a wide variety of magnetometers, ...
How to calculate the magnetic field of Earth. How does the magnetic field act like a shield? Why do magnets repel each other? How does a magnetic field sensor work? Why does magnetism exist? How is a magnetic field generated in general?

according to a paper published today (May 2) inCommunications Earth & Environment. The authors propose that the weakening of the magnetic field may have led to the increase in oxygen,
Professor: Think of earth as a one big giant magnet. So, earth is surrounded by a magnetic field, and we know that every magnet has a north and a south pole and things get oriented toward those poles. Earth is no exception, right? Male student: Right. Professor: Okay, keep in mind ...

Life as we know it could not exist without Earth's magnetic field and its ability to deflect dangerous ionizing particles from the solar wind and more far-flung cosmic rays. It is continuously generated by the motion of liquidironin Earth'souter core, a phenomenon called the geodynamo. ...

Physicist: High energy charged particles rain in on the Earth from all directions, most of them produced by the Sun. If it weren’t for the Earth’s magnetic field we would be subject to bursts of radiation on the ground that would be, at the very least, unhealthy. The more serious, ...
