Problem: You can make an electromagnet by wrapping wire around a wire and connecting the ends to a battery. If the battery is connected so that current wraps up in the front and down in the back, which direction will the magnetic field of the nail point? Answer: the magnetic field of the nail will point around the nail and in the same direction as the current. I don't know if this answer is correct. Was wondering if someone could please help me with this question? Thanks!
