Parts and what they mean

• x and y axes (z out of the page) (x और y अक्ष (z पृष्ठ से बाहर)) — Right-handed axes: î × ĵ = k̂.
• Element Δl = Δx î (1 cm), I = 10 A (अवयव Δl = Δx î (1 cm), I = 10 A) — At the origin, along +x.
• Point P on the y-axis (y-अक्ष पर बिंदु P) — r = 0.5 m, θ = 90°.
• Distance y = 0.5 m (दूरी y = 0.5 m) — Distance of P from the element.
• dB = 4 × 10⁻⁸ T along +z (dB = 4 × 10⁻⁸ T, +z के अनुदिश) — dl × r = Δx î × y ĵ = yΔx k̂, so the field points out of the page.
