Homework Statement
A 2400-turn solenoid is 2.4 m long and 10 cm in diameter. The solenoid current is increasing at 1.4 kA/s .
Find the current in a 5.0-cm-diameter wire loop with resistance 9.0 Ω lying inside the solenoid and perpendicular to the solenoid axis.
Repeat for a similarly oriented 15-cm-diameter loop with the same resistance, lying entirely outside the solenoid.
Homework Equations
M = µo (N/l) N' A'
I = emf/R
The Attempt at a Solution
The first part I was able to figure out it's the second part that I am struggling with. I tried doing the same equation I used.
Part A: .38mA
Here is what I plugged in:
(4pi(10-7)(2400pi)(.15)2)/ (4(2.4))*1400= 31.089*10-3
I = emf/R
31.089*10-3/9= 3.45 mA which is wrong
