Two cencetric coils, each of radius 2πcm and no of turns one are placed at right angle to each other. The currents flowing in coil are 3 A and 4 A respectively. The magnetic field induction ( in Wb/m² ) at the centre of the coil is B×10⁻⁵ .
Find the value of B.

Answer
Given,
The magnetic field induction ( in Wb/m² ) at the centre of the coil is B×10⁻⁵ .
Radius of two coils = 2πcm. = 0.02m
Currents in coils =>
In one coil the current is 3 A and
In another coil the current is 4 A respectively.
plz refer to the attachment for the Answer here
Remember
The SI unit of magnetic flux is Weber/m²
