Question

Current flow is defined as the movement of ________in a conductor. The discovery of magnetic lines of force generated by ____________ ___________ came after 1845.

Answer 1

Answer:

movement of electric charge, by Michael Faraday Magnetism.

Explanation:

• The electric current is the stream of charged particles and moves through an electric conductor. It can be measured by the electric change throughout the surface.  

• Moving particles are called charged carriers, the electric current in them are charged electrons that move through a wire.

• Michael Faraday discovered that the magnetic fields are generated by the electric current crossed by the line of force. Magnetism creates a magnetic current that came after 1845.
