description of :
I have been teaching Electromagnetics for Engineering college students and post graduates in physics for past decade.
Teacher's qualifications:
I am a post graduate in physics and at present a full time researcher and doing my Ph.D in Physics
's preferred teaching style:
My approach will be in explaining the basic concepts of electromagnetic step by step by simple methods and examples so that the student will get a grasp of the subject very easily.
