கோட்பாடு:

வலக்கை கட்டைவிரல் விதி:

  • இந்த விதியின்படி, நேரியல் கம்பி கடத்தியை வலது கையின் பிடியில் வைத்திருக்க வேண்டும் என்று நாம் கற்பனை செய்தால், கட்டைவிரல் மின்னோட்டத்தின் திசையில் இருக்கும், பின்னர் கடத்தியைச் சுற்றியுள்ள விரல்களின் வளைவு காந்தப்புலக் கோடுகளின் திசையைக் குறிக்கும்.

விளக்கம்:

  • கிடைமட்ட மின் பாதை வழியாக மின்னோட்டம் கிழக்கிலிருந்து மேற்கு திசையில் பாய்ந்தால், அதற்கு நேர் கீழே உள்ள ஒரு புள்ளியில் காந்தப்புலத்தின் திசை வடக்கிலிருந்து தெற்காக இருக்கும். எனவே விருப்பம் 2 சரியானது.
