For my physics project, I'm supposed to make an electromagnet that can raise/drop a paper-clip and the sum of all the voltages of the batteries I have used must not exceed 9 volts. Due to this, I feel as though my ability to create a functional project is lower than I originally thought. I was thinking of using a 4-5 volt battery for the electromagnet, and then another 4-5 volt battery to power a motor that will pull up/lower my electromagnet. Is there any way for me to increase the voltages on each of the batteries so that I can increase my project's ability to function?
