Answer 1

Answer #1

EMF = -NA * delta B / delta t

A = pi r²

EMF = N * pi r² * delta B / delta t

= [129 * pi * (2.99 * 10^-2)² * (94.3 mT - 57.1 mT)] / [0.193]

= 0.0698 V = 69.8 mV

1. calculate S = (1/1^2 + 1/2^2 + 1/3^2 + ... and so on), with 1% accuracy. Make the accuracy to be a parameter that can be assigned. For example, acc=0.01. Use "sum1" code as a template. You will need an idea for the "accuracy part" since N is not given. My suggestion: when you add a next term to S (let's say 1/n^2), check if dS/S >= acc. If 'yes' then you continue, if 'not' then you are done...
