alleryसोलेनॉइडची वळणे दुप्पट केली जातात आणि त्याचा प्रवाह अर्धा होतो. त्याची लांबी आणि गाभा अपरिवर्तित आहेत. त्याची चुंबकीय-क्षेत्र शक्ती कशी बदलते?
Aते अर्धे होते
Bते अपरिवर्तित राहते
Cते चौपट मोठे होते
Dते दुप्पट होते
Answer & Solution
Correct answer: B. ते अपरिवर्तित राहते
अपरिवर्तित भूमिती आणि कोरसाठी, फील्ड स्ट्रेंथ वळण वेळा करंटच्या प्रमाणात असते, त्यामुळे वळण दुप्पट आणि अर्धवट करंट कॅन्सल.
