Question 6 of 6

5.0 Points What is the magnitude of the magnetic field of the solenoid? A. 0.894 T B. 0.163 T C. 0.816 T D. 0.793 T E. 1.15 T

Explanation / Answer

r = 0.3 m , h =1 m , L =60 H, I =50 A

Question 4:

U =(1/2)Li^2 = 0.5*60*50*50 =7.5*10^4 J

Correct option is (C)

Question:5

V =pi*r^2.h

u = U/V = 7.5*10^4/(3.14*0.3*0.3*1) =2.65*10^5 J/m^3

Correct option is (A)

Question 6:

u =B^2/2uo

2.65*10^5 = B^2/(2*4*3.14*10^-7)

B = 0.816 T

Correct option is (C)
