You take a cone and wrap a thin wire around its curved surface, such that there are \(n\) turns per unit **slant** height. The half angle of cone is \(\theta = 45^{\circ}\). The wire carries a current \(I\). If the value of magnetic field created at the center of base is \(B_{0} \mu T\) , find \(\lfloor B_{0} \rfloor\)

**Details**

- \(\mu_{0} = 4 \pi \times 10^{-7}, I = 20, n = 5\) (All quantities given in the appropriate SI units)
