The probe shown below is sixty millimeters south of a wire. The induced field at that location is 1.20 G in the eastern direction. The Earth's magnetic field at the location is 0.50 G in the northern direction. How strong is the total magnetic field measured by the probe?

Net magnetic field at that position is given as 1.3 G

Explanation:

As we know that the magnetic field due to wire at the given position is

towards East

now magnetic field due to Earths field is given as

Towards North

so net magnetic field at the given position is vector sum of magnetic field due to these two fields

So it is given as

so we will have

where is the photo and the answer choices?
