(a) calculate the amplitude (largest magnitude) and direction of the magnetic field produced by the two power lines at the base of the tower, when a current of 2 ✕ 104 a in the left power line is headed out of the page, and a current of 2 ✕ 104 a in the right power line is headed into the page. magnitude t direction

T, up

Explanation:

If the height of power line, h = 60 m and distance between the power lines, d = 16 m, then we can use Pythagorean theorem to find the distance from power lines to the base, R.

m

We need to find magnetic fields calculated from two current carrying wires and add them to find magnetic field at the base of the tower.

Then,

in +y direction

Hence,

T

The direction is +y, that is, up.

c. magnitude and direction
