Question

A circular loop of wire of radius 0.5 m and resistance 0.0150 lies in the plane of the page. A magnetic field directed out of the page increases in magnitude linearly with time from 0.0 T att 0 ms to 1.2 T at t 6 ms. what is the magnitude of the electromotive force that is induced in the loop? 157 v You are correct Previous Tries Your receipt no s 147-8821 What is the magnitude of the electric current that is induced in the loop? 10400 A You are correct, Previous Tries Your receipt no s 147-1746 2) What is the direction of the electric current that is induced in the loop? Incorrect: counterclockwise Correct: clockwise You are correct. Previous Tries Your receipt no. s 147-7817 What is the magnitude of the magnetic field that the current in the loop creates at the center of the loop? Submit Answer Tries 0/99 At t 3 ms, what is the magnitude of the total magnetic field at the center of the loop? Submit Answer Tries 0/99

Explanation / Answer

magnetic field at the center B = uo*I/(2*r)

Bc = 4*pi*10^-7*10400/(2*0.5)

Bc = 0.01306 T <<<<-------answer

========================

magnetic field at time t = 3 ms

B = (1.2/6)*3 = 0.6 T

total magnetic field Bnet = B - Bc

Bnet = 0.6 - 0.01306

Bnet = 0.58694 T <<<---------answer
