1.	Diagram shows lengthwise 2 sections of a current carrying solenoid. X indicates current entering into the page, andindicates current emerging out of the page. Decide which end of the solenoid A or B, will behave as north pole. Give reason for your answer. Also draw field lines inside the solenoid.
Answer» SOLUTION :A = south pole, B = north pole. When north pole of a BAR magnet is brought near to end connected to negative terminal of BATTERY then solenoid repels bar magnet. It means the end of solenoid which is connected to negative terminal of the battery BEHAVES as north pole. For figure - Refer to Q. 2.
