What happens when an insulator is placed in an electric field? When an insulator, also called the dielectric, is placed in an electric field, it gets polarised. The polarised dielectric reduces the effective electric field. Can an insulator have an electric field? We define a conductor as a material in which charges are free to […]
Can we convert mass to energy?
Can we convert mass to energy? First discovered by Einstein more than 100 years ago, it teaches us a number of important things. We can transform mass into pure energy, such as through nuclear fission, nuclear fusion, or matter-antimatter annihilation. Can mass be converted into energy or can mass be destroyed? The total mass of […]

What does Lenz law state?
What does Lenz law state? Lenz’s law, in electromagnetism, statement that an induced electric current flows in a direction such that the current opposes the change that induced it. This law was deduced in 1834 by the Russian physicist Heinrich Friedrich Emil Lenz (1804–65). Lenz’s law. What are the four Maxwell’s equations? The statements of […]
Is there forces of attraction among the particles in all matter?
Is there forces of attraction among the particles in all matter? Particles of matter of the same substance, such as the same element, are attracted to one another. The force of attraction tends to pull the particles closer together. The particles need a lot of kinetic energy to overcome the force of attraction and move […]
What is Biot Savart law and its application?
What is Biot Savart law and its application? The Biot Savart Law states that it is a mathematical expression which illustrates the magnetic field produced by a stable electric current in the particular electromagnetism of physics. This law is applicable in the magnetostatic estimate, & is reliable by both Gauss’s (magnetism) and Ampere’s (circuital) law. […]
Can a nuclear power plant power a city?
Can a nuclear power plant power a city? A 1,000-megawatt power plant can meet the needs of a city the size of Boston or Seattle. ∎ Nuclear power plants require little land vs. and potentially more smog. How much electricity can 1 gram of uranium produce? The fission of 1 g of uranium or plutonium […]
