A student connects a battery to a wire and wraps the wire around an iron nail produced an electromagnet which action should the student take to increase the number of paper clips. The electromagnet can pick up.

Answer 1

The student should increase the number of wire wraps around the iron nail and/or increase the strength of the battery. This will increase the magnetic field produced by the electromagnet, allowing it to pick up more paper clips. Additionally, using a stronger iron core for the nail can also increase the magnetic strength of the electromagnet.
