Homework Help: Number of Loops in a Solenoid

  1. May 8, 2016 #1
    1. The problem statement, all variables and given/known data
    A solenoid has a radius of 10 cm and a length of 50 cm. What I need to know to begin the problem is the number of loops ion the solenoid.

    2. Relevant equations

    3. The attempt at a solution
    One turn will have a length of 2(pi)r. I need to know the thickness of the wire around. Once I have this I can take the length of the solenoid and divide it by this thickness to obtain the number of turns. I'm just not sure how to go about doing this. Help appreciated. Thanks.

    Please post the complete problem as it was given to you. As it stands there is not enough information in the problem statement to determine what you want, nor is it clear why you would need the number of turns on the solenoid. It is possible that there is some relevant context or other related information which you haven't shown.
