Question

Problem 33.16

The magnetic field inside a 5.0-cm-diameter solenoid is 2.0 T and decreasing at 3.10 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.

Part B

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

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

Problem 33.16

The magnetic field inside a 5.0-cm-diameter solenoid is 2.0 T and decreasing at 3.10 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.

Part B

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

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

d = 5cm , B =2 T , dB/dt = 3.1 T/s

Electric field E = (r/2)dB/dt

Part A: on the axis r =0

E =0

PAet B: r = 2.4 cm

E = (0.024/2)(3.1) = 0.0372 V/m
