Electromagnets have some advantages over permanent magnets. For example: they can be turned on and off the strength of the magnetic field can be varied These properties make electromagnets useful ...

It has numerous real-life applications, especially in developing and understanding devices and systems that involve electromagnetism. For example, it is used in designing transformers, inductors, and ...

This chapter presents three examples of electromagnetic (EM) simulation that illustrate the power and flexibility of the FDTD method. First, it describes a one-dimensional simulation of an optical ...
