Parts and what they mean

• Charging current i (आवेशन धारा i) — Flows towards the + plate, so its charge Q grows.
• Positive plate (धनात्मक पट्टिका) — Receives charge +Q; Q grows while current flows in.
• Negative plate (ऋणात्मक पट्टिका) — Carries −Q; electrons pile up here.
• Electric field E (विद्युत क्षेत्र E) — From + plate to − plate. As Q grows, E grows: dE/dt points along the current.
• Magnetic field B (circles) (चुंबकीय क्षेत्र B (वृत्त)) — Made by the displacement current ε₀ dΦ_E/dt; circles the axis, parallel to the plates, so B ⊥ E.
• Point M (between the plates) (बिंदु M (पट्टिकाओं के बीच)) — There is no wire here, yet a magnetic field is measured at M.
• Edge of the plates (पट्टिकाओं का किनारा) — E exists only inside this circle (fringing ignored).
• E pointing into the page (पृष्ठ के अंदर की ओर E) — We look along the current, so E (and its growth) points away from us.
• B circles (clockwise as seen) (B के वृत्त (देखने में दक्षिणावर्त)) — Thumb into the page → fingers curl clockwise. Same sense as around the wire outside.
• Point M (बिंदु M) — Inside the gap; B here is the same as just outside at P (for a loop enclosing the whole plate area).
