Fingers crossed

Im going to bed now:zzz: , but will have a look in the morning, hopefully to some help:biggrin: !

Thanks

It's hard to say, because you haven't described the experimental setup. The graph would be different for the field outside a wire and the field in a coil, for instance.
 
setup

The set up used was a compass on a support frame with 5 turns of wire around it. We used the tan (theta) to represent the magnetic field strength of the wire as it is directly proportional. The magnetic field strength of the Earth was an unknown constant.
