Question

_performed experiments to prove the magnetic effect of current

Answer 1

Answer:

This is what a scientist called Hans Christian Oersted also wondered. He was the first person who noticed the deflection of compass needle every time the current was passed through the wire. So, when electric current passes through a wire, it behaves like a magnet. This is the magnetic effect of the electric current

In 1820, Hans Christian Oersted performed an important experiment which showed the magnetic effect of Electric current.

• Put a material in a magnetic field.

• Run a current through this material.

• The magnetic field will create a "sideways" change in electric potential across the material - which you can measure.

• Using this change in potential and the size of the material, you get the magnitude of the magnetic field.
