How do you make an electromagnetic crane?

I need to make it with the help of 2 motors of DC 9V each and batteries which can range from 3V - 9V which can move about its axis and pick up a small amount of weight.
Need it fast!!!

Websearch "make an electromagnet" if you need to.

Look at toy cranes. See how they've arranged the strings which operate them. Replicate that, using the motors to wind or unwind the strings.

Attach electromagnet to working end of crane. Figure out how you're going to get power to it while having enough slack to move the magnet but not enough slack to tangle.
