Hey guys I want to build electromagnet which can lift up to 3 kg from 26 gauge copper wire, 12V battery (bike), so how many turns should I do and what will be length and radius of the solenoid?

Welcome to the PF. :smile:

A solenoid is not a very efficient electromagnet for lifting weights. You want the magnetic path to be fairly "closed" when lifting an object. You do that by presenting both poles at the same time on the same plane, and attaching a ferrous piece of metal to the two poles, hence closing the magnetic path...
