I have a physics lab and the main question is: 'How does the radius of the loops of a solenoid affect the magnetic field produced by the coil?' For my hypothesis, I wrote: "The larger the radius of a solenoid is,the weaker the magnetic field will be." I searched online and found out I was wrong but I'm keeping since it was my initial hypothesis. I'm stuck on the part where I have to write a procedure. My teacher states my procedure has to clear enough that "someone who knows nothing about it can follow and do it properly." That's the biggest hint I have and I'm lost. How do I write a procedure on how the radius of a selenoid effects the magnetic field. I know it has something to do with ampere's law which calculates the magnetic field, B= μoNI/L Please help!
