Two long wires are oriented so that they are perpendicular to each other, and at their closest they are 20.0 cm apart. what is the magnitude of the magnetic field at a point midway between them if the top one carries a curent of 25.6 a and the bottom one carries 5.4 a?

523.2 x 10^-7 T

Explanation:

distance between the two wires, D = 20 cm

d = D/2 = 10 cm = 0.1 m

Current in first wire, i1 = 25.6 A

Current in second wire, i2 = 5.4 A

The magnetic field due to a straight current carrying conductor is given by

Magnetic field due to the first wire

T

Magnetic field due to the second wire

T

The two magnetic field are perpendicular to each other

The resultant magnetic field is given by

B = 523.2 x 10^-7 T

where are the vectors ?

the answer is 3.1 his answer is wrong mines is right
