Physics problem
A small loop of area 8cm^2 is placed inside a long solenoid that has 850 turns/m and carries a sinusoidally varying current given by: i(t)=I0sin(wt),
Where i0=1.2A is the amplitude and w=200 rad/s is the angular frequency. the central axis of the loop and solenoid coincide (see a cross- section of the solenoid with the the small loop inside in the figure)
