For a given length l of wire carrying a current l, how many circular turns would produce the maximum magnetic moment ?

A circular coil of N turns is made of a conducting wire of a certain length . When a current I is sent through it , the magnetic moment is p , Another coil of 2N turns is made with the same wire and the same current is sent through it . The magnetic moment becomes p'. If p : p ' = n : 1 , what is the value of n ?

When a long wire carrying a steady current is best into a circular coil of one turn, the magnetic induction at its centre is B. When the same wire carrying the same current is bent into a circular coil of one turn, the magnetic induction at its centre is B. when the same wire carrying the same current is bent to form a circular coil of a turns of a smaller radius, the magnetic induction at the centre will be

The intensity of the magnetic induction field at the centre of a single turn circular coil of radius 5 cm carrying current of 0.9 A.
