Question

Нужно перевести правильно! Faraday knew from his long study of electricity that magnetism should be able to produce a current, as well as vice versa. In spite of his various failures, the idea of producing a current directly by magnetic action remained firm in his thoughts. One of his friends said later how at this period of his long life Faraday used to carry about with him in his pocket a small rough model of electro-magnetic apparatus. This consisted simply of an inch-long straight iron rod, or core, with some turns of copper wire wound round it. The basic idea he had in mind was this: if an electric current in a wire can produce a magnetic effect, why should not a magnet near a conducting wire produce an electric current? It was really a simple reversal of Oersted's 1820 discovery. By a happy choice, he decided to work not with a straight bar оr even a horseshoe magnet, but with a ring. This happened many times: each time the battery current came on, the needle linked to the opposite, unconnected coil deflected and then came to rest; each time the circuit was broken, the same effect was noticed. Instead he got it only when the magnetic field in the iron ring was changing – either switching on or switching off. Yet as the galvanometer needle showed, electricity, however weak, had flowed momentarily each time through the left-hand coil. It was new electricity where none existed before, and it had been produced, or induced, by electromagnetism.

Answer 1

Фарадей знал его длительного изучения электричества, магнетизма должен быть в состоянии произвести ток, а также наоборот. Несмотря на его различных сбоев, идея создания тока непосредственно магнитного действия остался тверд в своих мыслях. Один из его друзей сказал позже, как в этот период своей долгой жизни Фарадея используется для передачи с собою в кармане небольшой грубую модель электро-магнитного аппарата. Это состояли просто из прямой железный прут дюймов длиной, или ядра, с некоторыми витков медной проволоки, намотанной вокруг него.
Основная идея, которую он имел в виду вот что: если электрический ток в проводе может производить магнитный эффект, то почему бы не магнит рядом с проводом производить электрический ток? Это было действительно простой поворот 1820 открытие Эрстеда.
По счастливому выбора, он решил работать не с прямым бар Ор даже подковы магнита, но с кольцом.
Это произошло много раз: каждый раз, когда ток батареи пришли на, игла связана с противоположной, не связанных катушка отклоняется, а затем остановился; Каждый раз, когда цепь была нарушена, тот же самый эффект был замечен.
Вместо этого он получил его только тогда, когда магнитное поле в железном кольце меняется - либо включения или выключения.
Однако, как стрелка гальванометра показала, электричество, однако слабое, текла на мгновение каждый раз через левую катушку. Это было ново электроэнергии, где их раньше не было, и это было произведено, или индуцированной электромагнетизм.

Answer 2

Faraday, through his extensive study of electricity, understood that magnetism could produce an electric current, and vice versa. Despite facing various failures, he remained committed to the idea of generating a current directly through magnetic action. In fact, he used to carry a small rough model of an electro-magnetic apparatus in his pocket, which consisted of an inch-long straight iron rod (or core) with copper wire wound around it .

The basic idea behind Faraday's concept was that if an electric current in a wire can create a magnetic effect, then a magnet near a conducting wire should be able to produce an electric current. This was essentially a reversal of Oersted's discovery in 1820 .

Faraday chose to work with a ring instead of a straight bar or horseshoe magnet. Each time the battery current was switched on, the needle linked to the opposite, unconnected coil deflected and then came to rest. The same effect was observed when the circuit was broken. However, the effect only occurred when the magnetic field in the iron ring was changing, either when switching on or switching off. The galvanometer needle showed that electricity, albeit weak, momentarily flowed through the left-hand coil. This was the generation of new electricity where none existed before, induced by electromagnetism .

In summary, Faraday's experiments and observations led him to discover the phenomenon of electromagnetic induction, where a changing magnetic field induces an electric current in a nearby conductor .
