Goobta magnetic-ka ee magnet-ka birta ah

Maanta waxaan kula shaqayn doonaa darsiga 'The Magnetic Field of a Bar Magnet', kaas oo qayb ka mid ah cutubka magnets iyo electromagnets. Kahor intaadan bilaabin, waa inaad hore u garanaysid sida magnetku u shaqeeyo iyo in uu leeyahay laba cidhif (pole) oo kala duwan. Darsigani wuxuu ku barayaa sida loo sawiro goobta magnetic-ga ee ku wareegsan magnetka, laakiin hadda waxaad u baahan tahay inaad xasuusato in magnetku soo jiito birta.
