Electromagnet Help! How to Make a Small but very Strong Electromagnet???
I need to make a small Electromagnet, that uses minimum power (by that I mean the battery), but still has to be very powerful. I have a couple of questions that I need you to help me answer:
- Does the number of coils that is wound to the metal bar effect the strenght of the electromagnet?
- Does the wire gauge (20,24,28,30,34,36 wire gauge) make a difference is the strenght of the magnet?
- Does the voltage I supply to the coil effect the Electromagnet?
- What type of battery is best for an Electromagnet (AA, AAA, C, D), and what voltage (1,5V, 3V, 4,5V, 6V, 9V) ???
So is it better to just make 1 or more (3,4,5,6...) layers of wire winds???
Is it better to use thinner (36 gauge) or thicker wire (24 gauge)???
Thank you a lot!
