Good “glasses” from Oersted

H. C. The Danish physicist Oersted well demonstrated the essence of the previous sentence. In 1802 he discovered the relationship between electricity and magnetism, although with the help of the chiripa. But remember that chiripa, in the world of science, in general, does not work for free. To know how to take advantage of the chance it is essential to wear suitable glasses.

But in the thread. As thought for a long time, magnetism was an exclusive feature of steel and iron. In fact, these two metals were the only ones that attracted magnets and left them magnetized sustainably.

While physicist Oersted gave a conference in Copenhagen on the conversion of electricity into heat, he launched an electric circuit. The experiment did not come out as he wanted, but unintentionally (ay, dear chiripa! ), the physicist placed a compass next to the electrical circuit. The needle moved. In appearance, simplicity. Nothing else? Oersted had an expert mind and kept looking. When the electrical circuit was cut, the needle was moved again.

Go, go. Was the electric current generating magnetic force? What is going! It was not possible. But Oersted thought yes, risked and published the result of the experiment. Dozens of researchers then embarked on that unexpected relationship, eager. Oersted was correct. And also Pasteur!
