QUESTION
Need Formula or Expression for these:A generator is used to power a coil (Loop 1) that induces a current in a smaller coil (Loop 2) concentric with the first. The generator is comprised of a loop of wire with radius rg and Ng turns rotating at a frequency f within a constant magnetic field of magnitude Bg . Loop 1 has a radius of r1 with N1 turns, and is connected to the generator by two wires of length L . Loop 2 has a radius r2 with N2 turns, where r1>>r2 . All wires used within the system have resistivity ρ and diameter d .Part A – What is the maximum current in Loop 1Use the following two facts for the instantaneous change of a sinusoidal functionF=F0sin(2πft) ΔFΔt=2πfF0cos(2πft) F=F0cos(2πft) ΔFΔt=−2πfF0sin(2πft)Part B – What is the maximum current in Loop 2 induced by Loop 1?
