Hey guys, havent been on recently, and i thought i would post. i used to do a bunch of LEGO stuff but im done with that now. so ill be showing you how to make a simple fairly powerful electromagnet with 5 simple things.
Step 1: Materials
Here's what you'll need:
An iron rod/bolt or nail (i think mine is steel though couldnt find an iron one)
Copper wire (mine is solid but i think you can use threaded)
Power source (C battery works great)
im afraid to hook it up to a 120V wall AC/DC adapter afraid it'll flip the breaker haha.
Step 2: Winding the Wire
Start winding the wire tightly around your core. go most of the way down but dont completely cover it. I went down to the threads on my bolt and then put a nut on the end to keep the wire in place.
