5G10.00 | Magnets | | |
5G10.10 | magnet assortment | PIRA 500 | |
5G10.10 | magnet assortment | 5G10.10 | |
5G10.13 | letters on magnets | AJP 55(1),10 | Remarkably. the letters on the magnet are two the the three that can be read from either end or in a mirror. |
5G10.14 | various magnets | E-6c | Various magnets are pictured. |
5G10.14 | strong magnets | E-6d | Various strong magnets are shown. |
5G10.15 | lodestone | PIRA 1000 | |
5G10.15 | lodestone | 5G10.15 | Show that the lodestone attracts small nails. |
5G10.16 | lodestone suspended | PIRA 1000 | |
5G10.16 | lodestone | Er-5 | Magnetite is suspended in a magnetic field. |
5G10.16 | permanent magnets | E-84 | Pick up nails with a cobalt steel magnet. Also - levitation, elastic collisions. |
5G10.16 | lodestone | E-77 | Two pieces of magnetite
in paper stirrups come to rest on the magnetic meridian. Poles are identified
and repulsion and attraction are demonstrated. |
5G10.16 | lodestone | Disc 19-02 | A large lodestone
is suspended in a cradle with the south pole painted white. A bar magnet
is used to show attraction and repulsion. |
5G10.20 | break a magnet | PIRA 500 | |
5G10.20 | break a magnet | 5G10.20 | Show a magnet attracts nails, break it and repeat. |
5G10.20 | forming new magnetic poles | Er-12 | Break a magnet. |
5G10.20 | break a magnet | E-93 | Magnets of hard or hardened steel are broken and the pieces shown to be magnetized. |
5G10.20 | broken magnet | Disc 19-05 | A broken magnet still exhibits north and south poles. |
5G10.30 | Which is a magnet? | PIRA 1000 | |
5G10.30 | magnet and non-magnet | Es-9 | Two bars look alike, one is a magnet and the other is not. |
5G10.30 | Which is a magnet? | E-85 | With two similar bars of iron, one magnetized, use the end of one to lift the middle of the other. |
5G10.35 | two south pole magnet | E-79 | How to induce four poles in a knitting needle, the same poles at each end. |
5G10.36 | no pole magnet | 32-3.5 | Make a circularly polarized magnet in a steel ring and then break it in half. |
5G10.50 | lowest energy configuration of magnets | PIRA 1000 | |
5G10.50 | magnetic interactions | AJP 33(4),346 | Magnets
float in water with the north pole up constrained by a ring magnet. Place
up to 22 magnets in the tub and show equilibrium configurations. |
5G10.50 | lowest energy configuration | Disc 19-06 | Magnets
held vertically in corks are placed in a dish of water. When a coil around
the dish is energized, the magnets move to the lowest energy configuration. |
5G10.90 | cast magnetic field | TPT 3(5),226 | Iron filings are cast in gelatin. |
5G10.90 | magnetic monopole | Er-13 | Iron filings cast in acrylic over one pole of a magnet. |
5G10.90 | isolated pole | E-81 | An "isolated pole" is demonstrated by passing a long magnetized knitting needle through a cork and floating it on water. |
