if 2 north poles are brought together, is the resultant pole strength of the combination equal to the sum of their pole strengths?

No, when two north poles are brought together, the resultant pole strength of the combination is not equal to the sum of their pole strengths. In fact, two north poles repel each other rather than attracting.

To understand this concept, we need to consider how magnetic poles interact. Similar poles, whether north or south, repel each other, while opposite poles attract each other. This behavior is described by the law of magnetic poles.

If you were to bring two north poles together, they would push each other away, resulting in repulsion rather than attraction. Therefore, there is no resultant pole strength to consider since they do not combine or add up.

To further explore this topic, you can conduct a simple experiment by trying to bring two magnets with north poles together. You will observe that they repel each other, providing evidence that the resultant pole strength is not equal to the sum of their pole strengths.
