1. The problem statement, all variables and given/known data We did a lab where we measured the magnetic field strength of a wire coil versus the coil density of the wire coil, keeping current constant. We determined the relationship of B (magnetic field strength) versus n (coil density) to be direct. I need to explain why this is true physically (as in, beyond the formulas why does this actually happen), and I have no idea why. 2. Relevant equations β=μIn 3. The attempt at a solution I have no idea at all and need help!
