I am not able to understand reaction of magnetic force and how it is equal to qvb ?
DaleSpam said:When you start looking at fields you have to generalize Newton's third law. Basically Newtons third law expresses the conservation of momentum. While it may not make a lot of sense to talk about the force on a field, you can certainly talk about its momentum. Any force that the field exerts on matter causes an equal and opposite change in the momentum of the field.
The action reaction pair of magnetic force is a principle in physics that states for every action, there is an equal and opposite reaction. In this case, it refers to the interaction between two magnetic objects, where the force exerted by one object on the other is equal in strength but opposite in direction.
The action reaction pair of magnetic force is based on the fundamental law of magnetism, which states that opposite poles attract and like poles repel. When two magnetic objects are brought close to each other, their magnetic fields interact, resulting in a force that causes them to either attract or repel each other.
A common example of the action reaction pair of magnetic force is the interaction between two bar magnets. When two bar magnets are brought close to each other, their opposite poles (North and South) attract each other, while their like poles (North and North or South and South) repel each other.
The strength of the action reaction pair of magnetic force is determined by the strength of the magnetic fields and the distance between the two objects. The stronger the magnetic fields and the closer the distance, the stronger the force of attraction or repulsion between the objects will be.
Yes, the action reaction pair of magnetic force can be seen in many everyday objects and phenomena. Some examples include the interaction between fridge magnets, the operation of electric motors, and the Earth's magnetic field interacting with the magnetic field of a compass needle.
