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 ...

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 ...

The magnetic field lines of a bar magnet can be viewed by using compasses or by shaking iron filings onto a platform above the magnet. Place the magnet on top of the paper in view of the document ...

A tube filled with iron filings is magnetized and the magnetization is shown using a compass. Note: this demonstration can be shown on the overhead projector and is appropriate for large lecture halls ...

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.

IN some text-books and by some lecturers (e.g. Prof. A. Gray, as reported in NATURE of August 17, p. 379), the lines of magnetic force are said to be the curves along which iron filings are marshalled ...
