What did Faraday describe as 'lines of force'?

• A. gravitational waves
• B. electric current
• C. electric and magnetic fields
• D. magnetic flux lines

Answer: (C)

Lines of force are Faraday’s visual way of representing the invisible fields that cause forces at a distance. He used them to show how electric charges and magnets create fields, with the lines indicating the direction a positive test charge would move and how strong the field is where the lines are dense. This concept applies to both electric and magnetic fields, not just one or a single phenomenon. Gravitational waves aren’t described as lines of force, electric current is the flow of charge rather than a field visualization, and magnetic flux lines refer only to the magnetic field, whereas Faraday’s idea encompassed both electric and magnetic fields.
