A current `-` carrying circular loop of radius `R` is placed in the `XY-` plane with centre at the origin. Half of the loop with `xgt0` is now bent so that is now lies in the `XY-` plane

The magnitude of magnetic moment now diminishes

The magnetic moment does not change

The magnetic of B at (0,0,z), z gt R increases

The magnitude of B at (0,0,z), z gt gt R is unchanged
