Electromagnetic force is a special force that affects everything in the universe because it has an infinite-range attractive, like gravity; it is also a repulsive force which acts between charged particles. … If we have a positive and a negative electric charge, it will result in attraction.
Which force is attractive in nature?
(a) Gravitational force is always attractive in nature.
Which force is always repulsive in nature?
Gravitational force can be repulsive.
Is magnetic force always attractive in nature?
Both gravitational and magnetic forces are attractive and repulsive in nature.
Does electromagnetic force repel or attract?
Electromagnetism causes like-charged objects to repel each other and oppositely charged objects to attract each other. The electromagnetic force binds negative electrons to the positive nuclei in atoms and underlies the interactions between atoms.
Is magnetic force attractive or repulsive?
magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron.
Which force is both attractive and repulsive in nature?
Electromagnetism is both an attractive and repulsive force between particles with a property called charge, which come in two varieties – positive and negative. Objects of like charge will have a repulsive effect on each other, while objects of unlike charges will have an attractive effect.
Which is the strongest force in nature?
The strong nuclear force, also called the strong nuclear interaction, is the strongest of the four fundamental forces of nature.
Why gravitational force is attractive in nature?
In the case of gravity, mediated by spin 2 particles, charge is mass, which is always positive. Thus, q1q2 is always greater than zero, and gravity is always attractive. For spin 0 force mediators, however, there is no restriction on the charges and you can very well have repulsive forces.
Which forces can be either attractive or repulsive?
Electric and magnetic (electromagnetic) forces can be attractive or repulsive, and their sizes depend on the magnitudes of the charges, currents, or magnetic strengths involved and on the distances between the interacting objects. Gravitational forces are always attractive.
Which of the following force is not electromagnetic in nature?
The weight of a body is not electromagnetic in nature. The weight of the body is the Gravitational force acting on it and this force depends on the acceleration due to gravity.
Is gravity an electromagnetic force?
Gravity is not a force, even though it behaves like a force. Gravity is the result of energy curving the structure of spacetime. … So, as gravity is not a force, it can’t be an electromagnetic force. It does however have strong effects due to its effects on time.
What force attracts particles?
Gravity is the force that all objects with mass exert upon one another, pulling the objects closer together. It causes a ball thrown into the air to fall to the earth, and the planets to orbit the sun. The tiny particles that make up matter, such as atoms and subatomic particles, also exert forces on one another.
What causes magnetic attraction?
Magnetism is the force exerted by magnets when they attract or repel each other. Magnetism is caused by the motion of electric charges. Every substance is made up of tiny units called atoms. … In substances such as iron, cobalt, and nickel, most of the electrons spin in the same direction.
How do magnets attract?
It’s only when you hold unlike-poles together (a north pointing to a south) that magnets stick together (they are attracted). … Unlike-poles attract: When a north pole and south pole point together, the arrows point in the SAME direction so the field lines can join up and the magnets pull together (attract).
