Bar magnet ke beech mein dhaaga baandhkar use lohe ki cheezon se door khula latkao. Wo ghoomta, hilta aur aakhir rukta hai. Halka ghumaakar chhodo: wo hamesha uttar–dakshin disha mein rukta hai!
Jo sira uttar ki taraf hai wo magnet ka north pole hai; doosra sira, dakshin ki taraf, south pole. Isi se poles ko naam mile.
Compass ek chhoti magnetic sui hai jo N, E, S, W likhe dibbe mein khule ghoom sakti hai. Yatri, naavik aur pilot saikdon saal se raasta dhoondhne ke liye compass use karte aaye hain. Uttar pata ho to: uttar ki taraf mooh karke poorv daayein aur paschim baayein.
Tum apna compass bana sakte ho! Silaai ki sui ko magnet ke ek pole se kai baar ek hi disha mein ragadkar magnet banao. Use cork ke chhote tukde mein ghusaakar paani ke katore mein tairao: wo ghoomkar uttar–dakshin dikhaayegi.

Quick check
Khula latka bar magnet ruk gaya. Ye kis disha mein hai?
- Uttar–dakshin

Socho
Zoya ka compass steel ki almaari ke paas ajeeb disha dikhaata hai. Kyun?
Ek answer
Steel (lohe) ki almaari magnetic sui ko kheenchti hai aur use uttar–dakshin se hata deti hai. Compass ko lohe ki cheezon aur doosre magnets se door use karna chahiye.
