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.
