A long wire carrying a steady current is bent into a single coil such that magnetic induction at centre is B. Then same wire is bent to form a coil of smaller radius of 4 turns when magnetic induction at centre is B'. Then

A long wire carries a steadycurrent. It is bent into a coil of one turn such that magnetic induction at centre is B, then same wire is bent to form a coil of smaller radius of n turns when magnetic induction at centre is B' then

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

A long wire carrying a steady current is bent into a circular loop of one turn. The magnetic field at the centre of the loop is B. It is then bent into a circular coil of n turns. The magnetic field at the centre of this coil of n turns will be

A long wire carries a steady current . It is bent into a circle of one turn and the magnetic field at the centre of the coil is B . It is then bent into a circular loop of n turns. The magnetic field at the centre of the coil will be

A long wire carries a steady current, it is bent into a circle of 1 turn and magnetic field at the centre of the coil is B. It is then bent into a circular loop of n turns. The magnetic field at the centre of the coil will be

A long wire carries a steady current. It is bent into a circle of one turn and the magnetic field at the centre of the coil is B. It is then bent into a circular loop of n turns. The magnetic field at the centre of the coil will be :
