When a certain length of wire is turned into one circular loop, the magnetic induction at the centre of coil due to some current flowing is `B_(1)` If the same wire is turned into three loops to make a circular coil, the magnetic induction at the center of this coil for the same current will be

The magnetic induction at the center of a circular coil carrying current is

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 steady current flows in a long wire. It is bent into a circular lopp of one turn and the magnetic field at the centre of the coil is B. If the same wire is bent into a circular loop of n turns, the magnetic field at the centre of the coil is

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

The electric current in a circular coil of two turns produced a magnetic induction of 0.2 T at its centre. The coil is unwound and then rewound into a circular coil of four turns. If same current flows in the coil, the magnetic induction at the centre of the coil now is
