Explanation: The electromagnetic force is responsible for the interaction of charged particles. In particular, it describes how negatively charged electrons interact with positively charge atomic nuclei to form atoms.
What does electromagnetic force attract?
The electromagnetic force, also called the Lorentz force, acts between charged particles, like negatively charged electrons and positively charged protons. Opposite charges attract one another, while like charges repel. The greater the charge, the greater the force.
How does electromagnetic force affect an atom?
Oppositely charged particles attract each other, while like particles repel one another. Electrons are kept in the orbit around the nucleus by the electromagnetic force, because the nucleus in the center of the atom is positively charged and attracts the negatively charged electrons.
How does electromagnetism affect our daily life?
Exposure to electric, magnetic and electromagnetic fields (EMF), if they are strong enough, can lead to short term health effects. Exposure to low frequency fields that are strong enough can lead to dizziness, seeing light flashes and feeling tingling or pain through stimulation of nerves.
Why is electromagnetic force so important?
Electromagnetic forces are responsible for holding atoms together in solids and liquids, creating friction forces that allow you to walk across the room, producing light and radio waves, generating electricity, and so much more! Electromagnetic forces are responsible for making this bulb give off light.
What is a electromagnetic force in physics?
The fundamental force associated with electric and magnetic fields. The electromagnetic force is carried by the photon and is responsible for atomic structure, chemical reactions, the attractive and repulsive forces associated with electrical charge and magnetism, and all other electromagnetic phenomena.
How does the effect of the electromagnetic force in the nucleus compare with its effect on the atom as a whole?
As more protons are added to the nucleus, the electromagnetic force of repulsion between them gets stronger, while the strong nuclear force of attraction between them gets weaker. This puts an upper limit on the number of protons an atom can have and remain stable.
What is electromagnetic force in atom?
Electromagnetic force is a force of attraction or repulsion between all electrically charged particles. … Protons are found inside the nucleus at the center of the atom, and they give the nucleus a positive charge. (There are also neutrons in the nucleus, but they have no electric charge.)
How electromagnetic radiation affects matter when it is absorbed by matter?
The different parts of the electromagnetic spectrum have very different effects upon interaction with matter. … If electromagnetic energy is absorbed, but cannot eject electrons from the atoms of the material, then it is classified as non-ionizing radiation, and will typically just heat the material.
What is electromagnetic force give three examples of electromagnetic force from daily life?
All of the light from the Sun and other sources consists of photons which are the electromagnetic force carriers. Magnets and the Earth’s magnetic field, which protects us from harmful radiation, are aspects of the electromagnetic force.
What are the effects of electromagnetic radiation to living things and the environment?
Some forms of electromagnetic radiation, which is radiation found in different kinds of light waves, including ultraviolet light and X-rays, can cause damage to the DNA inside a living cell. When DNA is damaged by radiation, it can lead to cell death or to cancer.
How powerful is the electromagnetic force?
For instance, the earth and sun are far too distant from each other (billions of meters) for their nuclear forces to reach each other. In contrast to the nuclear forces, both the electromagnetic force and gravity have effectively infinite range* and die off in strength as 1/r2.
What factors affect the strength of forces?
The two factors are the mass of the objects and the coefficient of friction between them.
What are characteristics of electromagnetic force?
The properties of electromagnetic force are as follows:
- It obeys the inverse square law.
- It may be attractive or repulsive in nature.
- It is a long range force.
- The photon is the field particle of electromagnetic force.
- It is about 1036 times stronger than the gravitational force.
