Solution
The correct option is B Oersted
Oersted, Law is the law that a steady electric current creates a magnetic fieldaround it.[This was discovered on April 21, 1820, by Danish physicist Hans Christian Oersted when he noticed that the needle of a compass next to a wire carrying current turned so that the needle was perpendicular to the wire. Oersted investigated and found the mathematical law which governs how strong the field was, which is now called Oersted's law.
