Many grade school students perform a simple physics experiment by using iron fillings to outline a magnetic field. Seizing on their inner-child, physicists at the Max Planck Institute for Quantum ...

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 ...

You’ve probably heard the term magnetic gradient before, but have you ever seen one? Now you can in [supermagnetman’s] video, below. The key is to use very fine (2 micron) iron filings and special ...

Create your own magnetic slime and discover how ferromagnetic materials interact with magnetic fields. You'll learn about magnetism, viscosity, and chemical reactions while making a fascinating ...

The traditional method for visualizing magnetic fields, which your science teacher probably demonstrated at some point, is to sprinkle some iron filings onto a piece of paper and hold it over a magnet ...
