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 ...

Iron filings can be fun to play with, although we don’t think we’ve ever had any this fine. If you prefer your magnetic field visualizations to be higher-tech, we have the answer .

Iron filings are ferromagnetic materials that can be temporarily magnetized by a nearby magnetic field. The slime's viscosity allows it to move slowly at first, but the magnetic force becomes stronger ...

Iron filings: Sprinkle iron filings evenly around the wire. Hold down the power supply button to activate current. Tap the Plexiglas frame with your knuckles, screwdriver, or other tool to help the ...

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 ...

Art and science can sometimes have a magnetic attraction for one another. In a new set of images, Flint Weisser , an MFA candidate at New York's Pratt Institute, revisits the old iron-filings ...

Although we cannot see magnetic field lines, we can detect them using iron filings. The tiny pieces of iron line up in a magnetic field. Finding magnetic fields ...

Note: the filings are unlikely to damage or 'wipe' the magnetic strip, but use an old card just in case. Tilt the card and gently tap it so that iron filings slide across the magnetic strip.

The iron filings in the image become induced magnets when they are near the bar magnet. They lose most or all of their magnetism when they are removed from the magnetic field. Image caption, ...
