Question 7 of 10 A permanent magnet picks up an iron nail, magnetizing the nail. How is this system different from an electromagnet? O A. The nail is magnetized by a permanent magnet instead of by a solenoid with an electric current running through it. B. Magnetic induction does not occur in this system, but it does occur in an electromagnet. C. Electric current can run through the permanent magnet, but it cannot run through the nail. O D. The nail is magnetized by the interaction between electricity and magnetism instead of by a permanent magnet.
