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 mag… ...

Take magnetic fields – iron filings on a card will give you a 2D model, but a 3D visualization of the field would be much more revealing. For that job, this magnetic field following 3D carving ...

Bar magnets are permanent magnets close magnetAn object that produces a magnetic field which pulls on magnetic materials and attracts or repels another magnet. . This means that their magnetism is ...

Imagine a bar magnet inside Earth, more or less aligned with the axis, where the ends of that magnet lie close to the geographic North and South poles of the planet. The magnetic field lines ...

Iron Filings: Available from: Science supply stores like Home Science Tools, Carolina Biological, or Educational Innovations Some craft stores in their science project section Online educational ...

The magnetic field in a permanent magnet does tend to decay over time, but not with a predictable half-life as with radioactivity. “Permanent” or ferromagnetic materials have tiny regions, or ...

Cutting a bar magnet in half won't get rid of its poles. It'll just produce two magnets, each with a north pole that will be attracted to the other magnet's south pole, and vice versa.
