If 2 bar magnets are brought together, north to north and south to south is the resultant pole strength of the combination equal to the sum of their pole strengths?
Do you have answer?
To determine the resultant pole strength when two bar magnets are brought together, we need to understand the concept of magnetic fields and how they interact.
When the north pole of one magnet is brought close to the north pole of another magnet, or the south pole of one magnet is brought close to the south pole of another magnet, they will repel each other. Similarly, when the north pole of one magnet is brought close to the south pole of another magnet, they will attract each other.
However, it's important to note that magnetism is not merely about the poles themselves, but rather the magnetic fields they generate. The strength of a magnetic field is determined by the magnetic field lines.
Now, coming back to your question, when two bar magnets are brought together with the same poles facing each other (north to north or south to south), the resultant pole strength of the combination is not simply the sum of their individual pole strengths.
Instead, what happens is that the two magnets create a stronger magnetic field in the region between them. This causes the magnetic field lines to concentrate and interact, resulting in a combined magnetic field that is stronger than that of either individual magnet.
So, to answer your question, the resultant pole strength of the combination is greater than the sum of their pole strengths when two bar magnets with the same poles facing each other are brought together.
To observe and understand this phenomenon, you can conduct a simple experiment. Take two bar magnets and bring them close to each other with the same poles facing. Observe how they repel each other and the force between them. This will provide a visual demonstration of how the resultant pole strength is stronger than the sum of their individual pole strengths.
