संकल्पना:

दंड चुंबक

  • दंड चुंबकामध्ये लहान अंतराने विभक्त केलेले दोन समान आणि विरुद्ध चुंबकीय ध्रुव असतात. खांब अगदी टोकाला नसतात.
  • दोन ध्रुवांमधील सर्वात कमी अंतराला प्रभावी लांबी (Le) म्हणतात आणि बार चुंबकासाठी त्याच्या भूमितीय लांबी (Lg) पेक्षा कमी आहे.

चुंबकीय क्षेत्र आणि बलाच्या चुंबकीय रेषा

  • चुंबकीय ध्रुव किंवा चुंबक किंवा विद्युत प्रवाह वाहून नेणाऱ्या ताराभोवतीची जागा ज्यामध्ये त्याचा प्रभाव जाणवू शकतो त्याला चुंबकीय क्षेत्र म्हणून परिभाषित केले जाते.

F1 Jitendra.K 21-04-2020 Savita D1

  • चुंबकीय क्षेत्र रेषांच्या किंवा वक्रांच्या संचाच्या मदतीने दर्शवले जाऊ शकते ज्याला चुंबकीय शक्तीच्या रेषा म्हणतात.

स्पष्टीकरण:

  • दंड-चुंबकाच्या बाहेरील चुंबकीय क्षेत्र रेषांची दिशा उत्तर ध्रुवापासून दक्षिण ध्रुवापर्यंत असते तर चुंबकाच्या आत ती दक्षिण ध्रुवापासून उत्तर ध्रुवापर्यंत असते.
  • चुंबकीय क्षेत्र रेषेच्या जवळची डिग्री चुंबकीय क्षेत्राची ताकद निर्धारित करते. जेथे फील्ड लाइन जवळ असते, तेथे चुंबकीय क्षेत्र अधिक मजबूत असते.
