Part B

What is the electric field strength inside the solenoid at a point 2.40 cm from the axis?

Express your answer to three significant figures and include the appropriate units.

Part A)

E = (r/2)(dB/dt)
where

r = d/2 = 5 cm / 2 = 2.5 cm = 0.025 cm
dB/dt = 3.10 T/s

E = (0.025 / 2)*3.10

E = 0.03875 V/m

Part B

r = 2.40 cm = 0.240 m

dB/dt = 3.10 T/s

E = (0.024/2)*3.10

E = 0.0372 V/m
