Current magnetic effect
Any wire that has a current can generate a magnetic field around it, called the magnetic effect of the current. Magnetic phenomena and electrical phenomena have been studied separately. In particular, Gilbert's in-depth analysis of magnetic phenomena and electrical phenomena has concluded that electricity and magnetism are two distinct phenomena, and there is no consistency. Later, many scientists believed that electricity has nothing to do with magnetism. Even Coulomb also asserted that electricity and magnetism are two completely different entities that cannot interact or transform. But the question of whether electricity and magnetism have a certain connection has been lingering in the minds of some scientists who are interested in exploring.
