The sun's magnetic field will flip soon. Here's what to expect.As sunspots emerge on the sun's surface close to its equator, their orientations will match the old magnetic field, while ...
When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet. The field inside a solenoid is strong and uniform. The small magnetic field caused by ...
