| 11. | I break quite a few bar magnets and circular magnets, they all repel at the point they break.
|
| 12. | When placed in a magnetic field, the bar magnets quickly pivot, so they are parallel with the field.
|
| 13. | A loop of electric current, a bar magnet, an electron, a molecule, and a planet all have magnetic moments.
|
| 14. | The filaments seen before were all aligned in nearly the same direction, like iron filings near a bar magnet.
|
| 15. | ;Churchland's luminous room : " Consider a dark room containing a man holding a bar magnet or charged object.
|
| 16. | In this view, electrons can be thought of as bar magnets lined up next to one another, not touching.
|
| 17. | A permanent magnet, such as a bar magnet, owes its magnetism to the intrinsic magnetic dipole moment of the electron.
|
| 18. | When that part of the disk leaves the magnetic field, the bar magnets are no longer forced into lining up.
|
| 19. | If you look at the image at Magnet, you can see how the field lines go for a bar magnet.
|
| 20. | The iron atoms also act as bar magnets, and the directions of the magnetic fields usually alternated from layer to layer.
