The Correct Option is C

Approach Solution - 1

The correct answer is the magnetic effect of current. Hans Christian Oersted, a Danish physicist and chemist, was the first to discover the connection between electricity and magnetism in 1820. This pivotal experiment demonstrated that an electric current in a wire could produce a magnetic field around it, which was initially observed when a magnetic compass needle was deflected by a nearby electric current. This discovery led to the development of electromagnetism and had a significant impact on technology and physics as it laid the foundation for the study of electromagnetic fields.

Approach Solution -2

Hans Christian Oersted was the first to experimentally show that an electric current produces a magnetic field. In his experiment, he observed that a compass needle got deflected when placed near a current-carrying wire. This discovery established the link between electricity and magnetism.

Hence, his demonstration is related to: magnetic effect of current
