Answer:
The energy stored in the solenoid is 0.18J
Explanation:
We need to obtain the inductance in order to calculate the energy:
[tex]L=\µ_o*N^2*\frac{A}{L}\\\\L=4*\pi*10^{-7}*1000^2*\frac{(7.0*10^{-4}m^2)}{25*10^{-2}m}\\L=3.51mH[/tex]
The energy stored in the solenoid is given by:
[tex]U_g=\frac{1}{2}*L*i^2\\\\U_g=\frac{1}{2}*3.51*10^{-3}*10.0^2\\\\U_g=0.18J[/tex]
