Well my set up was just a straight wire, so I'm assuming I use the first equation since there are no visible windings? Either way I could rearrange in both equations, correct?

Oh, that makes total sense. I do have I, but N why do I need? Can't I use the first equation I posted?

Yup. 5. Plot a graph of magnetic field vs. the reciprocal of the distance from the center of the conductor. Use Logger Pro or another graphing tool. Page 2 of the experiment file is set up for this graph. 6. Calculate the permeability of the air from the slope of this graph. How does it...

For a magnetic fields lab I am asked to graph the data and from there, use the slope to find a certain value. For one of them, I am asked to plot the current (x) vs the magnetic field (y). The slope is supposed to give me a value, I have the slope, no clue what the value would represent...

Well I know conservation of energy, should I use that before I get to projectile motion? In other words, should I find out the energy and velocity and what not before the projectile than get to the projectile?

For my grade 12 physics class, we need to build a roller coaster. We are given a marble weighing 5 grams and it must be projected at the end of the track. It needs to land 0.5 m at a target when it is projected. Since the coaster is made entirely by myself the ramp in which it will be projected...
