What will happen if a bar magnet is placed close to another bar magnet?
We can say that the north pole of the hanging bar magnet will be repelled by the north pole of the second magnet. In this case then, the two poles that are closest to one another, the north and the south poles of these two bar magnets, are of opposite types. Therefore, they’ll attract one another.
Which pair of magnets has the strongest attraction between them?
The magnetic field generated by any magnet is always strongest at either pole. The magnetic force is equally as strong at both the north and south pole.
What is the end of a bar magnet called?
One end of any bar magnet will always point north. This end is called the north-seeking pole. What is a bar magnet? A bar magnet is a magnet of rectangular shape with a north and and south end, which are sometimes coloured different colours to indicate which end is which.
Why does the Earth act like a bar magnet?
The Earth acts like a very large bar magnet with its south-seeking pole near the geographic North Pole. That is why the north pole of your compass is attracted toward the geographic north pole of the Earth—because the magnetic pole that is near the geographic North Pole is actually a south magnetic pole!
How are magnets supposed to interact with each other?
Describe how magnetic poles interact with each other. Figure 1. Magnets come in various shapes, sizes, and strengths. All have both a north pole and a south pole. There is never an isolated pole (a monopole). All magnets attract iron, such as that in a refrigerator door. However, magnets may attract or repel other magnets.
Which is a universal characteristic of all magnets?
It is a universal characteristic of all magnets that like poles repel and unlike poles attract. (Note the similarity with electrostatics: unlike charges attract and like charges repel.) Further experimentation shows that it is impossible to separate north and south poles in the manner that + and − charges can be separated. Figure 2.
