sorry i forgot to mention the wire is vertical, also this isn't homework its a question from a past paper. my physics tutor is stumped on it, he said that you if you add them vectorially then the B-fields move in the same direction. I am really finding this hard its only the second question in...

hi thanks for that i tried it and i added the two B-field vectors together, i just want to know what do i do with this and if my sketch is correct thanks again i got B-field for the wire= 2.55x10^-6= u0(2)/2pi(0.05) added both B-fields together= 5.1x10^-11T

Homework Statement A current 2A flows in a wire. Value of horizontal component of Earth magnetic field in the region is 2x10^-5T. Small compass placed 5cm due north of the wire. Calculate the angle through which the needle deflects due to the current flowing in the wire. Assume u0= 4pi x 10^-7...
