If the power lines were Direct Current, sometimes used for efficient long distance transmission, then your compass would definitely be affected, and may be quite useless. The high currents in such a long distance DC line will generate a magnetic field.
With an Alternating Current power line, the alternating current itself should not cause any problem with the compass, but the steel of the towers themselves may certainly do so.

The lubber's line on a magnetic compass is a reference mark or line that helps users keep the compass heading aligned with the direction they are traveling in. By keeping the lubber's line pointed in the desired direction of travel, users can easily read their heading on the compass.
When constructing a line parallel to a given line, you will use a straightedge and a compass. First, place the compass point on a point not on the line and draw an arc that intersects the line at two points. Then, keeping the same compass width, place the compass point on the intersecting arc and draw another arc. Finally, draw a line through the two new intersection points, ensuring it is parallel to the original line.
The name of the line for the compass alignment is the index line. The line and the numbers around the outside edge can be used to plot a course to a distant object.
Yes definitely. Draw a line. Set the compass to the length of that line. Place the point of the compass on one end of the line and prescribe an arc. Place the compass on the other end of the line and prescribe a second arc which intersects the first arc. Where they meet, draw lines to each end of the first line and you will have an equilateral triangle.
The short luminous line in a magnetic compass, also known as the lubber line, helps the user accurately read the heading or direction the compass is pointing. By aligning this line with the desired direction or heading, users can navigate more effectively.

To create an 85-degree angle with a compass, first draw a straight line (the base of the angle). Place the compass point on one end of the line and draw an arc that intersects the line. Without changing the compass width, place the compass point on the point of intersection and draw another arc. Measure 85 degrees using a protractor from the base line to mark the angle, then draw a line from the vertex to this mark to complete the angle.
