Magnetic field - Wikipedia
The magnetic field is a field, produced by electric charges in motion. It is a field of force causing a force on material like iron when placed in the vicinity of the field. A magnetic field does not require any medium to propagate; it can propagate even in a vacuum.
Magnetic field | Definition & Facts | Britannica
A magnetic field is a vector field produced by a moving electric charge or a magnet. It has two basic ways of origin: by a current-carrying conductor or by the motion of electrons around the nuclei of atoms.

In celebration of the 25th anniversary of its release, the Magnetic Fields will perform 69 Love Songs in its entirety over the course of 2 nights, for the first time in two decades. The select run of dates will take place in Spring of 2024, with performances at MASS MoCA and in New York, Chicago, San Francisco, and Los Angeles.

A magnetic field is generated by a feedback loop: Current loops generate magnetic fields (Ampère's law); a changing magnetic field generates an electric field (Faraday's law); and the electric and magnetic fields exert a force on the charges that are flowing in currents (the Lorentz force).
