In this situation, the Biot-Savart Law tells us that the magnetic field at the center of the loop is proportional to the current in the loop multiplied by the length of wire used to make the loop. If this was the only issue determining the field (which it is not) we would expect the field at the center of the 60 cm loop to be larger than that at the center of the 25 cm loop because it takes a longer wire to make the bigger loop. If this was the only issue determining the field, and the two loops had equal currents, we would expect the field at the center of the 60 cm loop to exceed that at the center of the 25 cm loop by what factor

ride. You estimate the radius of thebig wheel to be 15 {/rm m}, and you use your watch tofind that each loop around takes 25 {/rm s}. a. What is your speed
