Question

Chapter 34, Problem 16E from Physics forScientists and Engineers A Strategic Approach (2nd) I am not sure what the corret formula is to solve this problemI tried all the ones that I could think of. Could someone offeranother formula that would solve the problem? Thanks Chapter 34, Problem 16E from Physics forScientists and Engineers A Strategic Approach (2nd) I am not sure what the corret formula is to solve this problemI tried all the ones that I could think of. Could someone offeranother formula that would solve the problem? Thanks The magnetic field inside a 5.0-cm-diametersolenoid is 2.0 T and decreasing at 4.40 t/s . What is the electric field strength inside the solenoid atpoint 1.80 cm from the axis?

Explanation / Answer

What is the electric field strength inside thesolenoid at point 1.80 cm from the axis?        {ElectricField @ r = 1.8*10-2} = E =             = {EMF Induced}/(2**r)             = (Flux/t)/(2**r)             = PI*(r2)*(B/t)/(2**r)             = r*(B/t)/2             = (1.8*10-2)*(4.4)/2             = 0.0396 V/m
