Secure | C HW 8 CH 28 Exercise 28.37 assignmentProblemiD 89546592 10 of 12 Part A Constants What is the magnetic feld at the center of this loop? A singlo clrcular current loop 18 0 cm in dameter carries a 300 A current P 209-10-s T Prevous Answer Correct Course Home Part B Suppose that we now connect 1200 of these loops in serles within a 620 cm length to make a solenoid 620 cm long What is the magnetic fleld at the center of this solenoid? Submit × Incorrect Try Again; 3 attempts remaining Part C

Explanation / Answer

A) B_loop = mu_o*i/(2*R) = (4*3.142*10^-7*3)/(2*0.18/2) = 2.09*10^-5 T

B) B_solenoid = mu_o*(N/l)*i = 4*3.142*10^-7*(1200/6.2)*3 = 7.29*10^-4 T
