When the North Pole of one bar magnet is near the South Pole of another bar magnet, they will attract each other. So, the correct option is C, attraction. This is because opposite magnetic poles attract each other, while like magnetic poles repel each other.
What is a magnetic field?A magnetic field is a region in space where a magnetic force can be detected. It is created by the movement of charged particles, such as electrons, protons, and ions. A magnetic field can be produced by a magnet, an electric current, or a changing electric field.
When the North Pole of one bar magnet is near the South Pole of another bar magnet, they will attract each other. This is because the magnetic field lines of the two magnets interact in such a way that they try to align with each other. Since opposite magnetic poles attract each other, the North Pole of one magnet will be attracted to the South Pole of the other magnet.
The magnetic force between the two magnets depends on the strength of the magnetic field and the distance between the magnets. The closer the magnets are, the stronger the magnetic force will be.
Therefore option C, attraction is correct.
