MCQ in Magnetic/Electromagnet PrinciplesĬontinue Practice Exam Test Questions Part 12 of the SeriesĬhoose the letter of the best answer in each questions.ĥ51.MCQ in Magnetic and Electric Quantities / Units.MCQ in Magnetic Field and Magnetic Flux.The measurement of magnetic flux is tied to the particular area chosen. It is a useful tool for helping describe the effects of the magnetic force on something occupying a given area. MCQ in Ohm’s Law, Kirchhoff Law, Coulomb’s Law, etc Magnetic flux is a measurement of the total magnetic field which passes through a given area.MCQ Topic Outline included in ECE Board Exam Syllabi The magnitude of the induced emf is proportional to the rate of change of the magnetic flux. An emf is induced in the coil because of this changing magnetic flux. Here negative sign shows that the emf is induced. The coils rotation causes the magnetic flux passing through the coil to change continuously from a maximum in one direction, to zero, to a maximum in the opposite direction, and so on. Because Faradays law states that the EMF of a coil is proportional to the negative rate of change of the magnetic flux through the coil. In Preparation for the ECE Board Exam make sure to expose yourself and familiarize in each and every questions compiled here taken from various sources including but not limited to past Board Exam Questions in Electronics Engineering field, Electronics Books, Journals and other Electronics References. Faradays law states that a coil with a larger magnetic flux will have a larger induced EMF, This is false. This is the Multiple Choice Questions Part 12 of the Series in Electricity and Magnetism Fundamentals as one of the Electronics Engineering topic. quadratic equation binomial theorem logarithms.Pre-board in Communications Engineering.
