संकल्पना:

उजव्या हाताच्या अंगठ्याचा नियम:

  • या नियमानुसार, जर आपण कल्पना केली की रेषीय तार वाहक उजव्या हाताच्या पकडीत धरला जाईल जेणेकरून अंगठा विद्युतप्रवाहाची दिशा निर्देशित करेल, तर वाहकाभोवती बोटांची वक्रता चुंबकीय बलरेषांची दिशा दर्शवेल.

स्पष्टीकरण:

  • जर आडव्या बलरेषांमधून प्रवाह पूर्वेकडून पश्चिम दिशेने वाहत असेल, तर त्याच्या थेट खाली असलेल्या एका बिंदूवर चुंबकीय बलरेषांची दिशा उत्तरेकडून दक्षिणेकडे असेल. म्हणून, पर्याय 2 योग्य आहे.
