Viva Question and Answers
Question 1
Explain the concept of energy stored in a magnetic field.
Energy stored in a magnetic field is the potential energy associated with the magnetic field. It is calculated by integrating the product of the magnetic field strength and the magnetic flux density over the volume of the magnetic field.
Question 2
What is the significance of Faraday's Law in electromagnetic theory?
Faraday's Law states that the induced electromotive force (EMF) in a circuit is directly proportional to the rate of change of magnetic field through the circuit. It is a fundamental principle in electromagnetic theory and is used to understand and analyze electromagnetic phenomena, such as electromagnetic induction.
Question 3
What is the role of displacement current in Maxwell's Equations?
Displacement current is the current that is induced by a changing electric field. It is included in Maxwell's Equations to account for the relationship between changing electric fields and magnetic fields.
