What magnetic rule states that like magnetic poles repel each other while unlike magnetic poles attract each other?
Answer and explanation
Correct answer: A. The fundamental law of magnetism
- Step 1: Magnetic poles always exist in dipoles (North and South). Step 2. Two North poles (or two South poles) repel, whereas a North pole and a South pole attract. Answer: The fundamental law of magnetism. Why not the others: Coulomb's law governs electrostatic charges; Faraday's law governs electromagnetic induction; Lenz's law gives induced current direction.
