Class 6 Science Chapter 4: Exploring Magnets (Hinglish Notes)
Ye chapter 5 lines mein
Magnet iron, nickel aur cobalt jaise magnetic materials ko kheenchta hai, par lakdi, plastic aur kaanch jaise non-magnetic materials ko nahi. Iski kheench do siron pe sabse zyada hoti hai, North aur South pole, jo hamesha jodi mein hote hain. Aazaadi se latka magnet uttar-dakshin disha mein rukta hai kyunki dharti khud ek bade magnet ki tarah kaam karti hai, aur magnetic compass isi se disha bataata hai. Ulte poles kheenchte aur same poles dhakelte hain, aur magnet ka asar non-magnetic cheezon ke aar-paar bhi jaata hai.
Reshma ki kahaani
Kerala ke ek tateeya shahar ki Reshma purane zamaane mein Kerala se masaale le jaane waale jahaaz pe kahaani likh rahi hai. Naavik raat mein taaron se disha jaante the, par uski kahaani mein toofaan taaron ko chhupa deta hai. Naavik raasta kaise dhoondhein? Use pata chalta hai ki yaatri magnetic compass use karte the. Reshma ne pencil box, purse aur school ke board ke duster mein magnets dekhe hain, aur ab wo aur jaanna chaahti hai.
Prakritik aur kritrim magnets
Purane naavikon ke magnet lodestones naam ke prakritik magnets pe based the, jo praacheen samay mein khoje gaye. Baad mein logon ne iron ke tukdon se magnet banaana seekha. Aaj magnet kai cheezon se bante hain, aur school lab, pencil box, sticker aur khilaunon ke magnet sab kritrim (artificial) magnets hain. Ye kai aakaaron mein aate hain.
Aur padho magnet kya hai mein.
Magnetic aur non-magnetic materials
Activity 4.1 mein alag-alag cheezon se bani vastuon ke paas magnet laaya jaata hai. Kuch chipak jaati hain, kuch nahi. Magnet ki taraf khinchne waali cheezein magnetic materials hain: iron, aur nickel aur cobalt dhaatuein, aur doosri dhaatuon ke saath unke kuch mishran. Na khinchne waali cheezein non-magnetic materials hain, jaise lakdi, rubber, plastic aur kaanch. Aur padho magnetic aur non-magnetic materials mein.
Magnet ke poles
Activity 4.2 mein iron filings ke upar rakha bar magnet zyaadatar filings ko apne do siron ke paas jama karta hai, aur beech mein bahut kam. Ye sire magnet ke poles hain: North pole aur South pole. Kisi bhi aakaar ke magnet ke poles pe sabse zyada filings chipakti hain. Ek hi pole waala magnet mumkin nahi: magnet ko todo to har tukde mein North aur South pole dono rehte hain. Aur padho magnet ke poles mein.
Disha dhoondhna
Activity 4.3 mein beech se dhaage se latka bar magnet hamesha uttar-dakshin disha mein rukta hai. Uttar ki taraf waala sira North-seeking pole (North pole) aur doosra South-seeking pole (South pole) hai. Aisa isliye hota hai kyunki dharti khud ek bade magnet ki tarah kaam karti hai. Usi tarah latki iron ki chhad kisi bhi disha mein ruk sakti hai, jisse pata lagta hai ki koi dhaatu ka tukda magnet hai ya nahi.
Magnetic compass isi khoobi ka istemaal karta hai. Isme pin pe santulit sui ke aakaar ka magnet hota hai jo aazaadi se ghoom sake, aur neeche dishaon waala dial; iska uttari sira aam taur par laal rang ka hota hai. Activity 4.4 mein tum silaai ki sui ko magnet banaakar aur paani mein cork pe tairaakar apna compass banaate ho. Bahut pehle Indian naavik matsya-yantra use karte the, tel ke bartan mein rakha machhli ke aakaar ka magnet bana iron. Aur padho compass kaise kaam karta hai mein.
Attraction aur repulsion
Activity 4.5 mein ek magnet gol pencilon pe rakha jaata hai taaki wo ludhak sake. Doosra magnet paas laane pe ulte poles (North aur South) kheenchte hain aur same poles (North-North ya South-South) dhakelte hain. Iron ki chhad dono poles se khinchti hai par kabhi dhakeli nahi jaati, isliye magnet ki pehchaan repulsion se hoti hai. Activity 4.6 mein magnet compass ki sui ko door ya paas ghumaata hai, aur Activity 4.7 mein beech mein lakdi, cardboard, plastic ya kaanch ki sheet rakhne se koi khaas fark nahi padta: magnet ka asar non-magnetic cheezon ke aar-paar jaata hai. Aur padho magnets mein attraction aur repulsion mein.
Magnets ke saath maza aur unki dekhbhaal
Reshma school mele mein khel lagaati hai: magnet se latakti pinon ki maala, tray ke neeche magnet chalaakar maze mein steel ki goliyan, ungliyan geeli kiye bina paani se paper clip nikaalna, aur do matchbox gaadiyan jo same poles aamne-saamne hone pe door bhaagti hain. Magnet kuch cheezon ko bina chhuye hila sakta hai. Poles N aur S, North ke liye safed bindi, ya North laal aur South neela rang se dikhaaye jaate hain.
Magnets ka dhyaan rakho. Unhe jodi mein, ek taraf ulte poles ke saath, beech mein lakdi ka tukda aur siron pe do soft iron ke tukde rakhkar sambhaalo. Unhe garam mat karo, giraao mat, hathaudi mat maaro, aur mobile phone aur remote se door rakho.

| Lodestone | Prakritik roop se milne waala magnet, jo praacheen samay mein khoja gaya aur shuruaati naavik use karte the. |
| Magnetic materials | Wo cheezein jo magnet ki taraf khinchti hain, jaise iron, nickel, cobalt aur unke kuch mishran. |
