What will you get from Electromagnetics Magnetostatics course?
Magnetic Gauss’s Law
Field in Materials
Magnetic Boundary Relations
Electromagnetics mainly deals with EM waves, their origin from Maxwell’s equations and their propagation. But the story of EM waves has to be started from the Electric field, Magnetic field, and their static and time-varying relations. Electromagnetics is revolving around Maxwell’s equations.
This course, Electromagnetic Magnetostatics, starts with the fundamental law of Magnetic Fields that is Biot-Savart’s Law. It is a basic law of our Electromagnetism which is already known to us. But exams like GATE and ES demand the various applications of the Law to find magnetic fields because of various current distributions. I have thoroughly explained Biot-Savart’s Law with all its applications like magnetic fields due to finite as well as infinite current carrying conductors. Not only up to the usual derivations, but I have molded the concepts with plenty of numerical so that you could easily tackle real GATE or ES problems.
The next fundamental law of the magnetic fields is Ampere’s Law. Actually, it is the logical counterpart of the Electric Gauss’s Law. I have discussed all the aspects of the Law to understand integral form as well as point form, intuitively. But most importantly, you must be able to use Ampere’s Law in real GATE or ES problems. So, with the help of numerical, I have dedicated ample amount of time to discuss the finest details for the use of the Law.
The next law in a row, for Magnetostatics, is Gauss’ Law. It is commonly known as Magnetic Gauss’s Law. As we have discussed Gauss Law for electric fields, here we have it for magnetic fields. There is a substantial difference between the electric Gauss’s Law and the magnetic Gauss’s Law. I have made you crystal clear about this difference! Of course, the knowledge of magnetic flux is required to study Gauss’ Law. So in this session, I have made you understand the magnetic flux by comparing it with the electric flux.
Magnetic Field doesn’t behave equally in all the Materials and hence you should know the behavior of the field within different materials. Here comes one of the important parts of Electromagnetics Magnetostatics, Magnetization of materials. I have explained all the necessary details related to magnetization of materials by comparing with the polarization of materials. Basically, you can easily remember all the terms related to magnetization by comparing it with polarization.
Finally, it may happen that the field is passing from one type of medium to another and hence Boundary Condition relations come into picture. This is the stuff which you expect directly in your GATE/ES exam. But you will experience the real significance of Boundary Conditions in the study of EM waves. I have made you clear all the details to get magnetic fields of the either side of the boundary surface with proper illustrative numerical. I have discussed a proper strategy to tackle such boundary relation problems. Using this strategy, I guarantee you that you will never make any mistake while dealing with boundary problems.
And finally, with my long experience of teaching many students, I know that usually, a student finds difficulty in understanding Electromagnetics because of a lack of visualizations of all these abstract things. So I have tried to solidify the concepts with the help of 3D illustrations.
Prerequisite for this Course “Electromagnetics Magnetostatics”
I would strongly suggest you the Basics course below before enrolling for this course.
Also it would be really helpful, if you already finished the Electrostatic course below before opting for this course. Because, we study most of the concepts of the Magnetic fields by comparing them with the respective concepts of the Electric fields.
