A rectangular loop of wire, L = 26.2 cm and W = 15.4 cm, carries a I1 = 1.83 A current and lies in a plane (d = 13.6 cm), which also contains a very long straight wire carrying a I2 = 10.5 A current.
I used this equation:
F1+F2 = mu0*I1*I2*0.262/(2pi)*(1/0.1361/0.290)=2.57*10^7 but this is wrong. Anyone know where I went wrong ?

You have a mistake in the calculations. My result is 3.93•10^6 N
