Answer:
20 * 10^-7 Tesla
Explanation:
Given Data:
Wire A passes through ( 4, 0 ) and has a current (i1) = 10 A
distance from origin ( r1 ) = 4
Wire B passes through ( 0 , 7 ) and has a current of 68A
distance from origin ( r2 ) = 7
The magnitude of the resulting magnetic field at the origin
Bnet = B1 + B2
Magnitude of Bnet = [tex]\sqrt{B_{1} ^{2} } + B^{2} _{2}[/tex]
Attached below is the detailed solution
