when a conductor carries a current at right angles to a magnetic field experiences a force at right angles to both the current and the direction of the field.
theres been no calculations so far. I am just suppose to give my best reasonable guess about the cause of the buzzing sound.

The motor principle is a fundamental concept in electromagnetism that explains how electric currents can produce rotational motion in a magnetic field. It is also known as the motor effect or the Lorentz force, named after the scientists who first described it.
Power lines can produce a buzzing sound due to the motor principle. As electricity flows through the power lines, it creates a magnetic field around the wires. When this magnetic field interacts with the Earth's magnetic field, it can cause the wires to vibrate and produce a buzzing noise.
The motor principle works by using the Lorentz force, which states that a charged particle moving through a magnetic field experiences a force perpendicular to both the direction of motion and the direction of the magnetic field. In the case of power lines, the electric current acts as the charged particles and the Earth's magnetic field acts as the external magnetic field, causing the wires to vibrate and produce rotational motion.
Yes, the motor principle has many practical applications in various devices, such as electric motors, generators, and even particle accelerators. It is a crucial concept in understanding and harnessing electromagnetism for technology and engineering.
No, the buzzing sound from power lines is not dangerous. It is simply a byproduct of the motor principle and does not pose any health risks. However, if the buzzing sound is accompanied by other issues like flickering lights or power outages, it is best to contact a professional to inspect the power lines for any potential hazards.
