Magnetic, Electric, And Gravitational Fields (1961)

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 create electric fields that can attract materials, and how gravity creates a gravitational field that pulls objects toward the Earth. The video emphasizes that fields are invisible but their effects can be observed, and it discusses how these fields extend outwards in all directions from their sources.
