Problem 30.20 MasteringPhysics 5 of 9 The magnetic field inside a 5.0-cm-diamete

Question

Problem 30.20 MasteringPhysics 5 of 9 The magnetic field inside a 5.0-cm-diameter solenoid is 2.0 T and decreasing at 3.60 T/s. Part A What is the electric field strength inside the solenoid at a point on the axis? Express your answer as an integer and include the appropriate units. EValue Units SubmitRequest Answer Part B What is the electric field strength inside the solenoid at a point 1.60 cm from the axis? Express your answer to three significant figures and include the appropriate units. EValue UUnits

Explanation / Answer

a) E = [r/2] * [dB/dt]

r = 0

E = 0

B) E = [0.016 / 2] * 3.60

= 0.0288 V/m

----------------------------------------------

A) time constant = L / Requ

Requ = L / T

1 / Requ = 1/500 + 1/R = T / L

1/R = [24 * 10-6 / 7.5 * 10-3 ]- [1/500]

R = 833.33 ohms
