Prof. Harish Chandra Verma is retired from Department of Physics at Indian Institute of Technology, Kanpur as a Professor. Prior to joining IIT Kanpur, he served Science College, Patna University (1979-1994) as Lecturer and Reader. His research interests had been in Nano fabrication using focused ion beam, Magnetism in Graphite on irradiation by ion beam, Nanosize (4 nm-20 nm) magnetic materials, Fe-based alloys, Earth Science etc. He has published 139 research papers in reputed journals. He has also written several books in Physics for School and College level. He has developed more than 600 physics experiments which can be used by teachers as DEMOs in their classrooms. He has also produced a set of 45 video lectures in Hindi at school level. Prof. Verma is Executive Committee member of Indian Association of Physics Teachers (IAPT) which works for physics education in instructor/tutor as announced in the senate of IIT Kanpur and was given appreciation letter from the Director.
The UG/professional courses include Nuclear Physics, Classical Mechanics, Quantum Mechanics, Electrodynamics, Review courses for PhD Students etc.

Utsahi Physics Teachers and DEMO experiments
Prof. Verma has developed more than 600 physics experiments which can be used by teachers as DEMO in their classrooms. Besides this, informal open-ended experimental activities have been developed where students are initiated in a direction and they conceive, assemble and perform experiments on their own. He conducts workshops of Physics school teachers where he impresses upon using DEMO-based physics teaching in which students can connect science with life. Through these extensive series of workshops Prof. Verma has motivated large number of Physics teachers and they have transformed a great deal the way physics is taught in schools. So far, Prof. Verma might have given training to more than 8000 teachers. According to the feedbacks received, about 800 of them have changed their approach and now they are enjoying Physics much more.Maxwell's equations are a set of coupled partial differential equations that, together with the Lorentz force law, form the foundation of classical electromagnetism, classical optics, and electric circuits. The equations provide a mathematical model for electric, optical, and radio technologies, such as power generation, electric motors, wireless communication, lenses, radar etc. They describe how electric and magnetic fields are generated by charges, currents, and changes of the fields.[note 1] The equations are named after the physicist and mathematician James Clerk Maxwell, who, between 1861 and 1862, published an early form of the equations that included the Lorentz force law. Maxwell first used the equations to propose that light is an electromagnetic phenomenon.
The equations have two major variants. The microscopic Maxwell equations have universal applicability but are unwieldy for common calculations. They relate the electric and magnetic fields to total charge and total current, including the complicated charges and currents in materials at the atomic scale. The "macroscopic" Maxwell equations define two new auxiliary fields that describe the large-scale behaviour of matter without having to consider atomic scale charges and quantum phenomena like spins. However, their use requires experimentally determined parameters for a phenomenological description of the electromagnetic response of materials.
The term "Maxwell's equations" is often also used for equivalent alternative formulations. Versions of Maxwell's equations based on the electric and magnetic scalar potentials are preferred for explicitly solving the equations as a boundary value problem, analytical mechanics, or for use in quantum mechanics. The covariant formulation (on spacetime rather than space and time separately) makes the compatibility of Maxwell's equations with special relativity manifest. Maxwell's equations in curved spacetime, commonly used in high energy and gravitational physics, are compatible with general relativity.[note 2] In fact, Albert Einstein developed special and general relativity to accommodate the invariant speed of light, a consequence of Maxwell's equations, with the principle that only relative movement has physical consequences.
