7. Imagine a wire is set to have a 6.0 Amp current traveling into the screen at position -2.5 m. A second wire is placed at +3.0 m and carries an 8.0 Amp current out of the screen. Calculate the strength of the magnetic field at x=0 m as well as at x = -3.0 m. Be sure to indicate direction. Show your work, and verify your result with the simulation. Reminder: the magnetic field due to a current-carrying wire is given as B = (μ0/2π)*(I/r).
Part 1.
To calculate the strength of the magnetic field at x=0 m
B=(0/2
)(I1/d1)+(
0/2
)(I2/d2)=(4

)(6/2.5)+(4
10-7/2
)(8/3)=1.01

Part 2.
To calculate the strength of the magnetic field at x=-3m
B=(0/2
)(I1/d1)-(
0/2
)(I2/d2)=(4
10-7/2
)(6/0.5)-(4
