I'm translating the problem, so sorry for the errors.(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

Radius of the upper circumference = 5cm

Radius of the lower circumference = 9cm

Resistance/meter = 3.00 ohm/meter

B is the magnetic field: DB/dt = 2.00 T/s

What's the magnitude of the current, and where does the current points to?

2. Relevant equations

EMF = [itex]-N \ \frac{\Delta \Phi_B}{\Delta t} \ \ \mbox{or} \ \ -N \ \frac{d\Phi_B }{dt}[/itex]

V = RI

3. The attempt at a solution
