A student connects a battery to a wire and wraps the wire around an iron nail to produce an electromagnet. Which action should the student take to increase the number of paper clips the electromagnet can pick up?
To increase the number of paper clips the electromagnet can pick up, the student should increase the number of coils of wire wrapped around the iron nail. Increasing the number of coils increases the strength of the magnetic field generated by the electromagnet, allowing it to attract and pick up more paper clips.
