Electrons align in a magnet due to their inherent magnetic moment, which arises from their spinning motion and orbital angular momentum. In a magnet, the magnetic moments of individual electrons align in the same direction, creating a magnetic field.

Certain materials are attracted to magnets because they have unpaired electrons that align in the presence of a magnetic field, creating a magnetic force that pulls them towards the magnet.
Electrons move in response to an electric force, which is generated by a difference in electric potential. This force causes electrons to flow from areas of high potential (positive) to areas of low potential (negative), creating an electric current.
A magnet gets excited when it is exposed to a magnetic field that aligns its magnetic domains in the same direction, enhancing its magnetic properties. This alignment increases the magnet's overall strength and allows it to attract or repel other magnetic objects more effectively.
The interaction of magnetic fields and electric currents creates a magnetic force that aligns the atoms in a material, making it magnetic. This alignment allows the material to attract or repel other magnets, which is what makes a magnet work.
The unit used to measure the electric force that causes electrons to move is called the volt, symbolized as V. Voltage is the potential difference between two points in an electric circuit that drives the movement of electrons.
