What effect does passing the negative pole of a magnet near a conductor have on electrons?

When a magnet is moved near a conductor, it creates a changing magnetic field, which can induce an electric current in the conductor through a process known as electromagnetic induction. This phenomenon is described by Faraday's law of induction.

In this context, when the negative pole of a magnet approaches a conductor, it influences the direction of electron movement within the conductor. The movement of the negative pole generates a magnetic field that interacts with the electrons in the conductor, causing them to move. This interaction effectively causes electrons to be driven away from the conductor, resulting in what is often described as being "expelled."

This induced motion of electrons is fundamental to the operation of many electrical devices, as it allows for the generation of electricity flowing through the conductor. Therefore, the assertion that electrons are expelled from the conductor captures the essence of what occurs when a negative pole of a magnet is brought close to a conductor, demonstrating how magnetic fields can interact with electric charges, thereby leading to the flow of current.
