    I am new a student in grade 9 and i have some problems about direct current motor science experiment .

    Could we use copper wire as conductor to roll .

    And my next question is why it moves when the current is passing . What is the reason ?

    If I understand your question correctly, bare copper wire would not be suitable for your motor windings. The windings would simply short out, so it needs to be insulated wire. In a real motor the windings are insulated by varnish. You could make one with rubber insulated wire, but that would limit the number of windings you could fit into your moter. It might work well enough just to demonstrate the principle.

    The operation of a d-c motor is explained in a lot of places on the internet. Just do a google search.

    You are welcome, and by the way, the varnish insulated wire is called magnet wire. If you can get some of that, it would work best.
