Define magnetic force and gravitation force with suitable examples
Answers
Answer:
Gravitational fields are determined only by the mass ( or mass-energy) of a body. ... magnetic fields are produced by charged particles in motion, and depend on the charge and velocity of these particles, but not on their mass. Magnetic fields are 'polar' fields with a North and South polarity.
Answer:
Explanation:
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. Electric forces exist among stationary electric charges; both electric and magnetic forces exist among moving electric charges. The magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other.
Gravitational force is one of the natural forces in the world.
Between any two masses consisting of matter, there exists a gravitational force of attraction proportional to their masses and inversely proportional to the square of the distance.
Formula of gravitational force is
F=r2GmM
Where, G = gravitational constant
Example is the force of attraction between Sun and Earth and between Earth and Moon. Due to this force, Earth revolves around the Sun and Moon revolves around Earth.
