## Newton’s third law with magnetic forces? Now while I was studying more about this matter, as I asked before when two bar magnets attract do they both their forces on each other? The answer was “YES.” Now, let me go indepth with this more and more, when two bar magnets of un-equal forces attract! Do they equally apply the same force or no? Imagine Magnet A capable of applying 50N of force while magnet B is applying 10N of force, they both attract! I think the two forces add up! What do you all think?

**The correct answer to the question is by increasing their masses, or by decreasing the separation distance between them.**

**EXPLANATION:**

Let us consider two bodies having masses M and M’ respectively . The two bodies are separated from their centre of masses by a distance of R.

As per Newton’s law of gravitation, the two bodies will exert gravitational force on one another. The gravitational force produced between them is calculated as –

Gravitational force

**Here, G is the gravitational force constant.**

From above, we see that the gravitational force is directly proportional to the product of masses of two bodies and inversely proportional to the square of separation distance between them.

**Hence, the gravitational force between two objects can be increased by increasing their masses, or by decreasing the distance between them.**
