The largest radio telescope FAST detects 90% circular polarization and rapidly changing linear polarization in the bursts of a fast radio burst (FRB) repeater, imposing new constraint on radiative ...

Solar flares accelerate energetic electrons that escape into interplanetary space, guided by the Parker spiral magnetic field ...

These measurements are complex and depend on several factors. The magnetic field that is measured with circular polarization is called the longitudinal magnetic field, and it corresponds ...

After this the wire is coiled into a circle, so the electric current produces a circular magnetic field. However, each coil increases the magnetic-field’s strength by many times. This creates a ...

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 ...
