Experimental physiscs II
1st degree and Bachelor-level of the Bologna process in Automotive Engineering - Torino
Objectives of the course
This course has the aim to complete tha basic knowledge discussed in Experimental physics I, focusing on engineering applications.
With lab experiences, this course teaches how to plan experiments, evaluate physical quantities, in order to represent and use them in
The student integrates the knowledge of Experimental physics I with electromagnetic phenomena.
A good knowledge of differential and integral calculus for functions with many variables and vector calculus of Experimental physics I is

- Autoinduction and mutual induction.
- RL circuits and energy in a magnetic field.
- Displacement flows. Maxwell's equations.
- Electromagnetic and plane waves.
Credit 4: Optic
- Reflection and refraction laws. Cluster angle,dioptric spherical surface, optical centred systems, lens.
- Light form electromagnetic point of view. Monochromatic waves.
- Group speed. Emission and absorption.

Practical Work Programme
Practicals are carried out in lecture halls with examples of topics studied. During the practicals are also discussed problems on a written
report of lab activites.
Laboratories and/or exercises
A second series of lab experiments are related to physical phenomena and interest of motor vehicle engineering is arranged.
- Strain-flow features of different materials and devices.
- Strenght measurement using Wheatstone's bridge.
- Measurement of capacity and inductance using RLC circuits
Professors are available to explain the students some topics of the program and of practicals, and to check, in an informal way, the
learning of the students. Students are divided into two groups.

The exam is constituted by a written paper and a subsequent oral test. The written paper may be replaced by a computer-based test.
The procedures for the oral test will be made known by the lecturer.
