Professor Sami Jaber receives Best Oral Presentation Certificate

Professor Sami Jaber, Department of Physics, An-Najah National University, participated in the 2nd International Conference on Physical Science and Technology (ICPST) in Doha, Qatar on the 7th-8th of January, 2015. Professor Jaber presented a research paper entitled: “Generalization of Faraday’s Law of Induction: Some Examples'', which shows that Maxwell’s equation of Faraday’s law of induction can be written in a more general form in physical space^*.

The steering committee has announced an award for the best research paper. Prof. Jaber’s paper was reviewed by the relevant supervising committee and has been granted the award for Best Oral Presentation.

Prof. Jaber’s visit agenda also included a meeting with the Palestinian Ambassador to Qatar, in which Prof. Jaber briefed HE on the An-Najah University's progress and development in various fields.

*Abstract:

A general form of the induced electromotive force due to time - varying magnetic field is derived. It is shown that the integral form of Faraday’s law of induction is more conveniently written in the covering space. The method used in this work relies on finding the modified magnetic field each time the circular path is traversed. This amounts to an additional time derivative of the magnetic field. Therefore, the induced electromotive force comes from the sum of all contributions coming from all winding numbers. The winding number to the (n+1^{) th} time - derivative of the magnetic field. It is also shown that the higher order terms are modulated by the self-inductance and resistance of the circuit. Some illustrative examples for time- dependent magnetic fields are presented: Sinusoidal, exponential, and step- function fields. In each of these examples, it is shown that the induced electromotive force could be written in closed analytical form that depends (among other things) on the ratio between the self-inductance and resistance of the circuit. Furthermore, in all these examples it is demonstrated that our result for induced electromotive reduces to the well- known result in the limit of the ratio of the self-inductance and resistance goes to zero. The conclusion of this work shows that Maxwell’s equation of Faraday’s law of induction can be written in a more general form in the physical space.
