Who discovered magnetic field of electric current?

Hans Christian Oersted discovered the magnetic field of electric current in 1820. He observed that a compass needle was deflected when placed near a wire carrying an electric current, showing a relationship between electricity and magnetism.


Who discovered a magnetic field can produce an electric current?

Michael Faraday discovered that a changing magnetic field can induce an electric current in a wire, which is known as electromagnetic induction. This discovery laid the foundation for the development of electric generators and transformers.


Who discovered that an electric current can act like a magnet?

Hans Christian Oersted was the first to demonstrate the relationship between electricity and magnetism in 1820 when he discovered that an electric current can create a magnetic field. This discovery laid the foundation for the development of electromagnetism.


How does an electromagnet utilize the interaction of electric and magnetic fields to generate a magnetic field when an electric current passes through it?

An electromagnet uses the interaction of electric and magnetic fields to create a magnetic field when an electric current flows through it. The electric current produces a magnetic field around the wire, and this field interacts with the magnetic field of the material inside the coil, strengthening the overall magnetic field.


Who is the scientist who discovered that electric current can affect the action of magnetic needle?
