The video explains the concepts of magnetic, electric, and gravitational fields using simple demonstrations. It shows how iron filings reveal the magnetic field around a magnet, how charged objects ...

The concept of magnetic field lines and magnetic fields was first studied and observed by Michael Faraday and by James Clerk Maxwell, who made great discoveries in the field of electromagnetism.

New research describes striking similarity of laboratory research findings with observations of the four-satellite Magnetospheric Multiscale Mission that studies magnetic reconnection in space. As on ...
