Depending on the Country / Type of Road. Normally its about 50 meters
Electric poles and wires are usually maintained and repaired by electric utility companies, such as power companies or municipal electric departments. These organizations have trained technicians and lineworkers who are responsible for installing, maintaining, and fixing electric poles and wires to ensure a reliable electricity supply.

If you want to know the standard for utility poles call your utility company. The electric company set their own standards. There are some required heights for electric cable in the code. For instance they must be no less than 8' above a roof.
The force of attraction or repulsion between magnetic poles is directly proportional to the strength of the magnetic poles and inversely proportional to the square of the distance between them. Like poles repel each other, while opposite poles attract each other. This force follows Coulomb's law, similar to electric charges.
The distance between the North and South poles
the minimium distance between the two meridians is at the poles because all the meridians comerge at the poles
In the US the standard height of a utility pole is 40 feet, and is buried six feet into the ground. The tallest utility poles have reached 120 feet because of clearance requirements in the area.
The magnetic attraction between two unlike poles increases as the distance between them decreases. This relationship follows an inverse square law, meaning that the force of attraction becomes stronger as the distance is reduced. Conversely, increasing the distance between two unlike poles weakens the magnetic attraction between them.
The distance between the center of a magnet and one of its poles is half the distance between the two poles when the magnet is symmetrically oriented. So in this case, the distance from the center of the magnet to one of its poles would be half of 58.8 cm, which is 29.4 cm.
It remains constant
