Parts and what they mean

• Compass needles (कम्पास सुइयाँ) — Each needle aligns with the local field (computed here). Joining the needle directions point to point gives a field line.
• Field lines (faint) (क्षेत्र रेखाएँ (हल्की)) — The needles are tangent to these lines.
• N pole (उत्तरी ध्रुव) — Needles near it point away from it (their N tip is repelled).
• S pole (दक्षिणी ध्रुव) — Needles near it point towards it.
