a magnet
Hans Christian Oersted's hypothesis was that an electric current produces a magnetic field around it. This hypothesis led to the discovery of electromagnetism and laid the foundation for the development of the field of electromagnetism.

The hypothesis that objects with more mass will exert a greater gravitational force on each other. The hypothesis that light is composed of particles called photons. The hypothesis that electric currents produce magnetic fields.
Hans Christian Oersted is known for his discovery of electromagnetism in 1820, which laid the foundation for the development of electric motors and generators. He also contributed to the understanding of chemical bonding and the nature of diamagnetism.
According to the concept of mastering physics, the electric field inside a conductor is zero.

Magnet. Oersted's hypothesis was proven correct when he observed that a compass needle placed near a wire carrying an electric current would deflect, indicating the presence of a magnetic field around the wire.
