Електрика — це розділ фізики, що вивчає електричні явища: взаємодію між зарядженими тілами, явища поляризації та проходження електричного струму. 3. Починаючи з кінця 19 століття, електричні явища відіграють дедалі більшу роль у виробництві й побуті. 4. Під дією кулонівської сили заряджені частинки переміщаються, утворюючи електричний струм. 5. Для вимірення напруги потрібно силу струму помножити на опір.
Listening
Dave Ansell is the science radio (“Naked Scientists”) science specialist is talking about where magnets obtain their energy.
a) Listen to his explanation and tick the features that he mentions.
|
1. In order to create a magnet, you’ve actually got to put some energy in. |
|
2. Iron, nickel and cobalt atoms have more electrons. |
|
3. Magnetic materials also alter the polarisation of light reflecting off their surfaces. |
|
4. You've got to rotate all the low atomic magnets inside the piece of metal |
|
5. The actual magnetism is actually caused essentially by electrons |
|
6. The atomic magnets would stay magnetized. |
|
7. Electrons can tunnel from a magnetic source material. |
|
8. Magnets can also weakly repel diamagnetic materials. |
b) Listen again and fill in the gaps. Explain what the words in italics mean.
1. I understand why __________ __________ magnets keep working as long as there is a current, but alignment in ferromagnets doesn’t use current.
2. And that takes some __________ and a magnet does have some energy
3. The electrons are going to keep on orbiting, as far as we know.
4. So the little atomic magnet is going to carry on forever.
5. But why is it then that some __________ get demagnetized over time?
6. So, the atomic magnet is still there, but instead of all pointing the same __________, they start to become more and more randomly __________.
