3. With the switch open try to pick up some paper clips and tacks. What happens?4. Close the switch and try to pick up the same paper clips and tacks. What happens?You can increase the power of your electromagnet by winding more turns of wire around the nail. You could also use ...
How to Make an Electromagnet Leave about a 4” end of wire loose and then tightly wrap the wire around the nail or bolt. Wrap it as many times as possible leaving just a small amount of exposed metal at each end. The more coils, the stronger the electromagnet. Secure with tape. Leave...
and you can use this to make an electromagnet by wrapping a current-carrying wire around a metallic core. In addition, you’ve found that a greater voltage or more wraps of wire increases the strength
