Maxium Allowable Current to (+/-) 2% ?
An experiment on the Earth's magnetic field is being carried out 7.00 from an electric cable.
What is the maximum allowable current in the cable if the experiment is to be accurate to 2.0 ? Assume that Earth’s magnetic field is .
B = [I*μ]/[2*Pi*d]
Check the picture to see how far I've gotten, but it's still wrong. I'm not sure how to attempt this problem.
