Natiijada casharka

Waxaan sharxi karaa sida magnet-yadu u soo jiitaan walxaha magnetic-ka ah, iyo sidoo kale sida ay u soo jiitaan ama u iska celiyaan magnet-yada kale.

Hordhac

Salaan, waxaan ahay Dr. George, casharkana waxaa loogu yeedhaa "Biraha birlabta" (Magnetic poles). Haddii aadan aqoon waxa ay yihiin, dhamaadka waad ogaan doontaa. Casharkani waa qayb ka mid ah cutubka "Birlabyada iyo korantada birlabta" (Magnets and electromagnets). Waxaan rajeynayaa inaad ku raaxaysato. Ujeeddada aad rabto inaad ku gaarto dhamaadka casharku waa inaad sharxi karto sida birlabyadu u soo jiitaan walxaha birlabta leh iyo sidoo kale sida ay u soo jiitaan ama u iska celiyaan birlabyada kale.

Muuji qoraalka

All magnets have a north–seeking pole and a south–seeking pole. Unlike magnetic poles attract each other, and similar magnetic poles repel each other. Magnetic materials are attracted to both north–seeking and south–seeking magnetic poles. Just three metal elements (iron, cobalt and nickel) are magnetic; other metal and non–metal elements are not magnetic. A north–seeking pole will point towards the North Pole because Earth has a magnetic field.
