Statement 1:  Magnetic field due to an infinite straight conductor varies inversely as the distance from it.Statement 2: The magnetic field at the centre of the circular coil is zero.

The magnetic field at a point due to current flowing through an infinitely long conductor is given byB=μ04π  2lawhere, A is the distance of that point from conductor. Now according to right hand thumb rule, it follows that magnetic field is in the form of concentric circles, whose centres lie on the straight conductor . The magnetic field at the centre of the circular coil is μ0i2r
