Electromagnetics catches an eye of many students before their undergraduate studies but at the same time it takes somewhat not-so-friendly form very soon in early years of engineering. However, in reality, every branch of electrical and electronics engineering requires knowledge of electromagnetics.

In this talk, we would try to discuss some of the problems in applied electromagnetics. First of all, we can try to cover an interdisciplinary problem where electromagnetics can be used to analyze the forces in manufacturing. Accuracy is very important aspect of any manufacturing technology. Wire Electric Discharge Machining is a manufacturing method where cutting takes place due to heat produced by the spark discharges between the tool (wire) and the workpiece. We will discuss how the electromagnetic analysis can help to get better understanding of vibrations of the wire due to Lorentz forces.

Solar photovoltaic installations are increasing worldwide as the push for the green energy is increasing. However, analysis of electromagnetic compatibility aspects of solar photovoltaics is important to make sure that they operate reliably and do not face consequences such as ban on products. We would discuss how the analysis of EMC issues in photovoltaics can be done.

High voltage engineering is rather an old branch within electrical engineering. Recently, it has come to light again because of HVDC push due to increased renewables like offshore wind farms. We would discuss the standards which the HVDC inverters or cables need to follow. Further, the design of shields for the equipment to be used in HVDC substation would also be discussed
