A single circular current loop 10.0 cm in diameter carries a 2.00-A current. (a) What is the magnetic field at the center of this loop? (b) Suppose that we now connect 1000 of these loops in series within a 500-cm length to make a solenoid 500 cm long. What is the magnetic field at the center of this solenoid? Is it 1000 times the field at the center of the loop in part (a)? Why or why not?
Free Compression Lab Continuation: We have seen that with four molecules in our gas box, a 50/50 split (2 on each side) has the most microstates but we do observe other configurations (all on one side for example) Just like with our coins, this would be true with real gas molecules too Why do we not see other options in our everyday world: we never see significant numbers of gas molecules on one side of a room! Something must happen when we increase the number of molecules from four to the 1028 in this room. To understand why, we will be looking at the fraction of the time that the split is within 10% of 50/50, i.e. “What fraction of the time is the number of molecules on the left between 40% and 60% of all of the mo
