While preparing for the JENPAS UG 2025 exam, you must pay attention to the Physics section and important topics, such as Electromagnetic Theory, since these topics are regularly asked in recent question papers. Solving a vast number of focused questions makes you not only familiar with the JENPAS UG 2025 exam pattern but also improves accuracy and speed. This study material gives a well-organised collection of solved examples together with clear-cut explanations and tried-and-tested methods in sync with current exam trends. Most toppers highlight the need for constant practice and intelligent revision to score high. With the JENPAS UG 2025 Electromagnetic Theory Sample Questions with Solutions PDF, you can refine your preparation, enhance problem-solving skills, and beat others.

What to Expect in JENPAS UG Electromagnetic Theory Questions

Electromagnetic Theory is a highly scoring topic in the JENPAS UG Physics section, typically having 3 to 5 multiple-choice questions annually. Topics include formula-based questions, conceptual-type questions, and practical applications, hence making this chapter highly lucrative if practised thoroughly. Based on previous trends, you would be able to expect more questions regarding electric fields, Gauss's theorem, magnetic effects of current, and electromagnetic waves. As the difficulty level is somewhat towards application-based type questions, a sound grasp of the principles will be beneficial.

Key Topics to Focus On

• Coulomb’s Law and Electric Field concepts
• Properties of Magnetic Materials (Ferromagnetic, Diamagnetic, Paramagnetic)
• Gauss’s Law with Electric Flux Problems
• Potential, Capacitance, and Their Applications
• Electromagnetic Induction Principles
• Basic Understanding of Maxwell’s Equations
• Magnetic Effect of Current, including Biot–Savart Law

List of JENPAS UG 2025 Electromagnetic Theory Sample Questions with Solutions

The following is a collection of a few important JENPAS UG 2025 Electromagnetic Theory Sample Questions with Solutions based on question banks, previous year's papers, mock tests, and study material:

1. Write Coulomb's Law and explain its significance.

Answer: Coulomb's law is the electrostatic force between two point charges. It is directly proportional to the charges and inversely proportional to the square of the distance between them.

1. Explain Fleming's left-hand rule for the force on a current-carrying conductor in a magnetic field.

Answer: Extend the middle finger, forefinger, and thumb perpendicular to each other. Forefinger along the direction of the magnetic field, middle finger along the direction of the current, and thumb along the direction of the force on the conductor.

1. Describe wave propagation in lossy and lossless dielectrics.

Answer: Lossless media do not lose any energy; the wave travels with undiminished amplitude. Some of the energy is lost as heat in lossy media, represented by the attenuation constant α.

Study Tips for Electromagnetic Theory Questions in JENPAS UG 2025

If you are studying for Electromagnetic Theory while pursuing your JENPAS UG 2025 preparation , then you require a shrewd combination of concepts, equations, and practice. It is a tough subject since the topic will challenge memory as well as its speedy application, hence speed as well as comprehension will become your topmost priorities.

• Work through basic definitions and SI units such as electric potential, magnetic field strength, and flux. These are typically asked directly.
• Practice direction and diagram questions, including direction of the field and direction of force questions, have been a recurrent feature of past JENPAS exams.
• Keep up to date with the basic electric and magnetic field equations in the usual conditions, i.e., wire loops, circular loops, and solenoids.
• Practice managing time by attempting JENPAS UG previous years’ question papers and JENPAS UG sample papers within time limits, while you become accustomed to the pressure of the exam.

To perform well in the Electromagnetic Theory section of JENPAS UG 2025, you must be regular with subject-wise questions, past year papers and concept formation simultaneously. Utilise free online mock tests, NCERT-based exercises, and solution videos on genuine websites. Periodic revision, elimination of doubts, and practice of a minimum of 50 to 70 practice questions per week will enhance accuracy and result in higher scores in this section.
