A question about electro magnets and solenoids?
This question was longer but this is the third time I'm trying to post it internet problems XD SO i guess if you need more info I can provide more.
Any way I was wondering if anyone had any tips for making stronger electro magnets and solenoids. I want to make some that can lift and move like 5 pounds, I have no idea if this is a lot or not so if it's unrealistic... woops.
Any way for the magnet I've been using nails I could find around the house, C batteries and magnet wire I got from radio shack, and the solenoid I use the same power and wires but I took apart some random free pen form a gym and use a random long screw that only had threads around the tip and sorta wiggled around inside the pen case. In both cases they only could hold up or move about 8 ounces. any ideas on making them stronger? or am I just being unrealistic?
