If we unwound and rewound a coil will number of turns remain
same??

Let N be the initial no of turns
Circumfrenceof one of the trun is 2πR
where R is the radius of the circular turnso length of the wire=N(2πR)If we unwound and rewound the coil again with same radius then no of turns will remains samebecause length of the wire remains same
