# A conical solenoid!

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)
