![]() ![]() Similarity - Field Strength: Field strength is a measure of the force experienced by a test object per unit of mass or charge. Electric fields can be either attractive or repulsive (depending on the type of charge), while magnetic fields are associated with the motion of charged particles and can change in direction.ĭifference - Forces: Gravitational fields result in a gravitational force acting on objects with mass, while electric fields lead to electric forces on charged objects, and magnetic fields result in magnetic forces on moving charged particles. In contrast, electric and magnetic fields are associated with electrical charges and moving charges (currents). In these cases, the fields describe how a force (gravitational, electric, or magnetic) would affect an object placed at a particular point in space.ĭifference - Nature of the Field: The gravitational field is associated with the force of gravity and is always attractive. The force between two objects attracted by magnetism is far greater than the feeble gravitational attraction between them. Snyder Los Angeles, California1 It is argued that there is a connection between the fundamental forces of electromagnetism and gravitation. A field is a physical quantity that has a value at every point in space. A Connection Between Gravitation and Electromagnetism Douglas M. Similarity - Field Concept: Gravitational, electric, and magnetic fields are all described using a field concept. Here's how they are similar and different: The gravitational field is conceptually similar to the electric and magnetic fields in physics, but it arises due to gravity, not electric charges or moving charges (as in the case of electric and magnetic fields). The size of the force is the same as the force that would be measured if all the mass or charge is concentrated at a point at the centre of the sphere.Home iit-jee comparison between gravitational field electric field and magnetic field Comparison between Gravitational Field, Electric Field and Magnetic Field The forces of inertia, gravitation, electric force, and magnetic force are represented by a single. Coulomb's law is the product of two masses, whereas Newton's law of universal gravitation is the product of two charges. The reason for the similarity is that these laws are derived from a single law of force. Coulomb's constant kis very large, so that even small charges can result in noticeable forces. The universal constant G is very small and in many cases the gravitational force can be ignored. The electric force can attract or repel, depending on the charges involved, whereas the gravitational force can only attract. Question 6 (1 point) Which of the following is NOT a similarity or difference between Coulomb's law and Newton's law of universal gravitation? The forces act along the line joining the centres of the masses or charges. Electrostatic force and gravitational force have associated fields, but magnetic force does not Gravitational force is stronger than electrostatic force, and both follow the inverse square law. ![]() All three require opposite poles or charges, but only gravitational force follows the inverse square law. ![]() Magnetic force and gravitational force follow the inverse square law, with electrostatic force needing two opposite charges. Question 3 (1 point) Which statement best describes differences and similarities among electrostatic force, magnetic force, and gravitational force? All three follow the inverse square law, with electrostatic force and magnetic force needing two poles or charges. ![]()
