Need help with a school project

M_G

Hello. I am currently a student and need help in the subject of electromagnetism. What can be the maximum weight a homemade electromagnet can carry given by the power source of a 2 x 1.5 AA Battery? Afterwhich, may I ask for the type of wire, core, and additional tips for creating this magnet?

  • Look up how much current your batteries can supply. Look up what is the smallest diameter wire that can carry that current. Based on the resistance of that wire calculate how much wire would it take for the resistance to be equal to the battery voltage divided by the current. Wind the maximum number of turns you can with that wire. Wind on a core that won't saturate. Calculate the inductance. Calculate the magnetic field. Calculate the force on the material you wish to attract.
