Likewise, a wire passing through a magnetic field creates an electric current within the wire. This is the basic principle that allows electric motors and generators to operate. In the Earth (see ...
Would a dramatic change in the Earth's magnetic field affect creatures that rely on it during migration? Late on a January night in 1993 I found myself on a beach on the Pacific coast of Costa ...
The compass needle points in the direction of the Earth's magnetic field, or the magnetic field of a magnet. place the plotting compass near the magnet on a piece of paper mark the direction the ...

Scientists create magnetic device to capture electricity from Earth’s rotational dynamicsA wild idea has been proposed to generate electric power from Earth’s rotation with the help of magnetic fields. A new ...
From there, the other directions can be figured out. Without the Earth’s magnetic field, this useful phenomenon would not occur. Whilst the geographical and magnetic north poles aren’t always ...
As we near the spring equinox, also known as the vernal equinox, on March 20, the Earth's magnetic field and solar wind align, creating an increased chance of seeing the colorful auroras in the ...
Russell-McPherron Effect: Why "Cracks" In Earth's Magnetic Field Mean We Get Peak Auroras At Equinox
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 ...
