Two conductors of infinite length carry a current i each which varies with time according relation i ine They are parallel and separated by a distance 2a A circular conducting rin of radius a and having a resistance 1 22 length in the plane of wires lies between the two straig conductors and insulated from them as shown A Mutual inductance of system is 2 a B Mutual inductance of system is u a C Net magnetic field at the centre of circle is always zero D Net magnetic field at the centre of circle increases with time c
