AMagnets produce electricity
BA current-carrying conductor produces a magnetic field around it
CTwo parallel wires always repel each other
DA magnetic field exerts no force on a current-carrying conductor
Answer & Solution
Correct answer: B. A current-carrying conductor produces a magnetic field around it
Hans Christian Oersted (1820) noticed that a compass needle near a current-carrying wire deflected. The conclusion: electric currents produce magnetic fields. This was the first link between electricity and magnetism, eventually unified under Maxwell's equations.
Option D describes Faraday's induction (1831), the reverse direction of the same coupling.
