Description : Why is electromagnetism so important?
Description : How can a magnetic field be used to generate an electric current?
Answer : Magnetic field can be used to generate electric current on a condition that it is on a rate of changing magnetic flux. (Faraday's law)
Description : What are the electromagnetic waves used in remote control?
Description : Define: (i) Electromagnetism (ii) Magnetic flux.
Answer : i)Electromagnetism : It is the magnetism generated by electricity. OR It is defined as the phenomenon associated with electric and magnetic fields and their interactions with each other. ii) Magnetic flux : The total number of magnetic lines of force in a magnetic field is called magnetic flux.
Description : Gauss' law of electricity, Gauss' law of magnetism, Faraday's law of induction, and Amperes' law form the basic equations of electromagnetism. This combination is collectively known as: w) Coulomb's equations x) Volta's equations y) Fermi's equations z) Maxwell's equations
