Pictures may enliven us, but other data, such as information about magnetic fields, add a huge amount to our understanding of ...

Earth is encircled by two donut-shaped bands of particles called the Van Allen belts, where energetic protons and electrons from the sun are trapped by the planet’s magnetic field. These ...

A research team led by Prof. ZHANG Xin from High Magnetic Field laboratory, the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, has revealed how magnetic properties vary in ...

That the magnetic orientation ... magnetic field has only just begun. Spin torque can be used both to switch magnetic orientation 3 and to cause the magnetization to ring at microwave frequencies ...

They found an odd ring around the ... core is made up of liquid iron and nickel and surrounds the solid inner core. Its churning movements create Earth's magnetic field, which surrounds the ...

If it weren’t for the magnetic field that surrounds our planet ... It’s composed predominantly of iron and nickel which are, importantly, in fluid form. As heat from the red-hot inner core radiates ...

A coil with an iron core is called an electromagnet. The iron core increases the coil’s magnetic field strength. A simple electromagnet is made by coiling wire around an iron nail. An iron core ...
