Which effect of current is associated with magnetizing nearby materials?

• A. Chemical Effect
• B. Physiological Effect
• C. Magnetic Effect
• D. Heat Effect

Answer: (C)

Current flowing through a conductor generates a magnetic field around it. That magnetic field can realign the magnetic domains in nearby ferromagnetic materials, turning them into magnets or strengthening their magnetization. This is the magnetic effect of current. The other effects describe different outcomes: chemical effects involve electrochemical reactions, physiological effects relate to how electric currents affect living tissue, and heat effects come from power dissipated as heat in resistance. So magnetizing nearby materials is the magnetic effect.
