Question

В чем состоит суть опыта эрстеда

Answer 1

если вблизи проводника с током расположить магнитную стрелку то стрелка регистрирует наличие магнитного поля
Вывод
Там где есть электрический ток всегда возникает магнитное поле

Answer 2

The Essence of Ersted's Experiment

The essence of Ersted's experiment lies in the discovery of the relationship between electricity and magnetism. In 1820, Hans Christian Ersted, a Danish physicist, observed that a compass needle deflected when placed near a wire carrying an electric current. This observation led to the understanding that an electric current produces a magnetic field, thus establishing the fundamental connection between electricity and magnetism.

Ersted's experiment demonstrated the interplay between electricity and magnetism, laying the groundwork for the development of electromagnetism and the subsequent advancements in the field of physics. This pivotal discovery has had far-reaching implications in various scientific and technological applications, shaping the modern understanding of electromagnetism and its practical utilization
