Yes, opposite charges attract.
And now, a closer look
Opposite charges indeed attract, and this fundamental principle in physics plays a significant role in explaining various phenomena in our everyday lives and the natural world. The concept of opposite charges attracting each other has been established through experimental observations, mathematical models, and theoretical explanations. Let’s delve deeper into this intriguing topic and explore some interesting facts.
-
Coulomb’s Law: The force between two charged objects is governed by Coulomb’s Law, which states that the force of attraction or repulsion between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
-
Electrostatic Forces: Opposite charges attract each other due to the electrostatic force, which is the force exerted between electrically charged particles. This force can be estimated using Coulomb’s Law and is responsible for interactions between charged particles, such as electrons and protons.
-
Everyday Examples: We encounter instances of opposite charges attracting in our daily lives. For example, when you rub a balloon on your hair, the balloon gains a static charge. As hair strands are neutrally charged, they are attracted to the charged balloon, resulting in your hair sticking to it.
-
Particle Interactions: Opposite charges are pivotal in the stability of matter. Protons and electrons, which carry opposite charges, form the basic building blocks of atoms. Electrons, being negatively charged, are attracted to the positively charged protons in the atomic nucleus, creating a balanced atomic structure.
-
Magnetic Attraction: While discussing opposite charges attracting, it’s also worth noting that the principle extends beyond electrical charges. In magnetism, opposite magnetic poles (north and south) attract each other due to the interaction of magnetic fields. This phenomenon is governed by similar principles of force and attraction.
To further emphasize the significance of opposite charges attracting, consider the following quote from celebrated physicist Richard Feynman:
“Electricity is not something within a wire; it is a force between charged particles, and this force propagates through electromagnetic fields.”
In conclusion, opposite charges do indeed attract each other. This fundamental principle can be explained through Coulomb’s Law and serves as the basis for numerous phenomena observed in the natural world. From the interactions between subatomic particles to the sticking of static-charged objects, the attractive force between opposite charges plays a crucial role in shaping our understanding of physics.

In the video “Why Do Like Charges Repel & Opposite Charges Attract?”, the speaker delves into the fundamental concept of like charges repelling and opposite charges attracting in physics. The explanation lies in the separation of electric charges and the resulting interaction between them. This behavior is observed not only in everyday objects but also in various particles, making it a fundamental principle in the standard model of particle physics. The video offers a concise understanding of this concept and its importance in the field of physics.

If a positive charge and a negative charge interact, their forces act in the same direction, from the positive to the negative charge. As a result opposite charges attract each other: The electric field and resulting forces produced by two electrical charges of opposite polarity.
It’s been know for hundreds of years, since Coulomb discovered it, that "opposite signs electric charges" attract each other, not "same sign electric charges"
The reason that like charges repel and opposite charges attract is because of the way that they interact with each other. Like charges repel because they push each other away, while opposite charges attract because they pull each other towards each other.
Opposite charges attract each other (negative to positive). Like charges repel each other (positive to positive or negative to negative). Most of the time positive and negative charges are balanced in an object, which makes that object neutral.
When two charged objects are brought close to one another, depending on the type of charge each one carries, they either attract or repel one another. When two objects have the same charge, they repel one another, and when they have opposite charges, they attract.
When the rod is touched to the electroscope, the electroscope becomes negatively charged. Thus, when the electroscopes are brought near each other (one charged with the plexiglass rod and one charged with the polyethylene rod) the attract since they have opposite charge.
Oppositely charged objects will exert an attractive influence upon each other. In contrast to the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other.
Opposite (unlike) charges attract one another. Like charges repel one another. This is often demonstrated using plastic rods charged with a duster. Two identical plastic rods have like charges. The hanging rod turns away from the other rod.
Do opposite charges attract or repel? The electric field and resulting forces produced by two electrical charges of the same polarity. The two charges repel each other. … As a result opposite charges attract each other: The electric field and resulting forces produced by two electrical charges of opposite polarity.
This will happen because the larger body will induce an opposite charge to smaller body and they will start attracting to each other.
The two opposite charges always attract each other as the force of direction of the charges acts in the same direction.
