OVERVIEW

The Physics II course deals with two of the main subjects of classical physics: thermodynamics and electromagnetic theory.

 

AIMS AND CONTENT

LEARNING OUTCOMES

The specific training objective is to provide the student with the ability to solve elementary but concrete problems. This implies that the student must know how to distinguish between fundamental concepts (electric and magnetic fields and forces, works, Gauss's laws, Ampere's, Faraday's, ...) and more specific issues (motion of charges in electromagnetic fields, cylindrical condensers, .. .) demanding a thorough understanding of fundamental concepts.

AIMS AND LEARNING OUTCOMES

The course aims to provide the basic concepts of thermodynamics and electromagnetism, both to deepen the cultural formation of the students, and to provide the technical tools relevant for their future work activity. The students will learn to apply the basic concepts to the solution of simple problems modelling concrete situations that could occur in the maritime workplace and ship management. 

PREREQUISITES

The basic mathematical knowledge necessary to follow the lectures is
•    Calculus, first and second order (quadratic) equations
•    Basic trigonometry
•    Functions of a real variable and their derivatives
•    Basic planar and solid geometry
Other mathematical tools will be introduced or recalled during the lectures.

 

  •  

Teaching methods

Lessons comprising both theory and exercises.

 

SYLLABUS/CONTENT

Definition of the magnetic field through the Lorentz force. Forces on a current-carrying conductor. Mechanical moment acting on a current conducting loop. Magnetic moment of a spire. Methods for determining the magnetic field produced by currents: Ampère’s law, Biot-Savart’s law.

Flux of the magnetic field through a closed surface and through an open surface bounded by a closed line. Faraday's law. Self-induction. RL and RLC circuits. Energy density of the magnetic field.

 

RECOMMENDED READING/BIBLIOGRAPHY

Any "General Physics" book at university level discusses the subject of the course.

For definitness, the main reference for the course is: D. Halliday, R. Resnick, J. Walker, Fundamentals of Physics 10E – Theory

EXAMS

Exam description

EXAM: the exam consists in a written and an oral part.

The written exam precedes the oral exam and a passing grade is required to be admitted to the oral exam.

The dates of the oral part of the exam will be agrreed upon with the students.  

 

 

Assessment methods

Students will evaluated on:

- the knowledge of the course contents

- problem solving skills

- ability to handle and comunicate the arguments discussed during the lectures
