A radian is the measure of an angle at the centre of a circle subtended by an arc, whose arc length is equal to the radius of the circl.. There is no problem with that. I'm going to do a demonstration for you whereby I'm going to use the earth's magnetic field and a loop that you see here that has 42 windings. So my capital N is 42. Not just two like here, but 42. And it is circular. It has a radius. I think it's about thirty centimeters. Here you have it. It's about thirty centimeters. So the area, pi r squared, which is my capital A, pi r squared is about 0.28 square meters. You may want to check that. I use the ...
a certain amount, a certain distance-- unimportant how much. And I know that I when I do that that there will be a pull-- non-negotiable. I put a mass, m1, here, and I measure the acceleration that this pull causes on this mass immediately after I release it. I can measure that. So I measure an acceleration, a1. Now I replace this object by mass m2 but the extension is the same, so the pull must be same. The spring doesn't know what the mass is at the other end, right? So the pull is the ...
