Placing a magnet on your refrigerator might hold up your calendar, but researchers have now found that placing one outside a plasma chamber causes a localized, fireball-like structure. This work may ...

How can you produce a magnet with exactly the right magnetic field? A research team now has a solution: for the first time, they have created magnets with a 3D printer. Today, manufacturing strong ...

Electric and magnetic fields are both components of an electromagnetic field. These two components occupy different planes relative to the cause of the electromagnetic field, for example a moving ...

Earth’s magnetic field protects us from deadly space radiation. What if it were drastically weakened, as a precursor to flipping upside down? I mean, it has before … many, many times.. PBS Space Time ...
