Parts and their functions

• Solenoid (coil of insulated copper wire) (परिनालिका (विद्युतरोधी ताँबे के तार की कुंडली)) — Many circular turns wound closely in the shape of a cylinder.
• Field inside: uniform (अंदर का क्षेत्र: एकसमान) — Parallel straight lines — same strength and direction at all points inside.
• Field outside (बाहर का क्षेत्र) — Curves from the N end to the S end, just like a bar magnet.
• N and S ends (N और S सिरे) — One end behaves as a north pole, the other as a south pole. Reverse the current → poles swap. (Here the front strands carry current downward, so the right end is N.)
• Current direction (धारा की दिशा) — Use the right-hand rule on any turn to get the field direction inside.
