Most of the time, the Earth and Sun’s magnetic fields are misaligned, leaving our planet’s field less open to the aurora-causing effects of the solar wind. However, towards the equinox, the two fields ...

Aurora borealis is one of the coolest astronomical events that we can see with the naked eye. It makes the sky glow beautiful colors, and auroras are just random enough to be exciting occurrences. But ...

nor the sun or stars, which were known to serve them as navigational aids. Clearly they were acting on something invisible, and Fromme deduced it must be the Earth's magnetic field. Numerous ...

When an electric current passes through a metal wire, a magnetic field forms around that wire (see diagram at right). Likewise, a wire passing through a magnetic field creates an electric current ...

If it weren’t for the magnetic ... the field acts as a protective bubble, interacting with harmful particles just beyond the outermost layer of Earth’s atmosphere. It deflects the cosmic rays that ...

In a groundbreaking discovery, scientists from Beihang University in China have detected a phenomenon typically associated with Earth's magnetic field 100,000 kilometres (62,000 miles) beyond our ...

A magnetic field is invisible, but it can be detected using a magnetic compass. A compass contains a small bar magnet on a pivot so that it can rotate. The compass needle points in the direction ...
