1) Electromagnetics 
Electromagnetism, or the electromagnetic force is one of the four fundamental interactions in nature. The other three are the strong interaction, the weak interaction, and gravitation. This force is described by electromagnetic fields, and has innumerable physical instances including the interaction of electrically charged particles and the intera...

electromagnetics noun the branch of physics concerned with electromagnetic phenomena
In physics, the properties and interactions of magnetism and electric currents. A current flowing through a conductor produces a magnetic field around the conductor; a varying magnetic field interacting with a conductor produces a current in the conductor. This is known as the electromagnetic effect
