# PHYS1022 Electricity and Magnetism

## Module Overview

The major concepts covered are: - The abstraction from forces to fields using the examples of the electric and magnetic fields, with some applications - The connection between conservative forces and potential energy - How charges move through electric circuits - The close connection between electricity and magnetism, leading to the discovery of electromagnetic waves. - the integral form of Maxwell's Equations

### Aims and Objectives

#### Learning Outcomes

##### Knowledge and Understanding

Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:

• the use of Coulomb's law and Gauss' law for the electrostatic force
• the relationship between electrostatic field and electrostatic potential
• the use of the Lorentz force law for the magnetic force
• the use of Ampere's law to calculate magnetic fields
• the use of Faraday's law in induction problems
• the basic laws that underlie the properties of electric circuit elements

### Syllabus

Electric field - Coulomb's law, - Superposition principle - Electric field and electrostatic potential, - Field patterns and equipotentials, - Gauss' law, - Capacitance, conductors and insulators, - Analogy to gravity Magnetic field - Vector product - Lorentz force - Ampere's Law - Electric motors - Magnetic field patterns - Magnetic induction (Faraday's law) - Dynamo - Mutual and self inductance - Transformers Electric circuits - Ohm's law and resistance.

### Learning and Teaching

#### Teaching and learning methods

The course consists of 24 lectures presenting the basic material using chalk and talk plus powerpoint slides for historical background. There are also12 problem classes allowing hands on problem solving with help on hand. Assessed problems are through Mastering Physics, an online system that provides hints as you progress. The course is also supported by the first year small group tutorial sessions. A mid-term test encourages enagement early in the course.

### Assessment

#### Assessment Strategy

Weekly course work will be set and assessed in the normal way, but only the best ‘n-2’ attempts will contribute to the final coursework mark. Here n = the number of course work items issued during that Semester. As an example, if you are set 10 sets of course work across a Semester, the best 8 of those will be counted. In an instance where a student may miss submitting one or two sets of course work, those sets will not be counted. Students will however, still be required to submit Self Certification forms on time for all excused absences, as you may ultimately end up missing 3+ sets of course work through illness, for example. The submitted Self Certification forms may be considered as evidence for potential Special Considerations requests. In the event that a third (or higher) set of course work is missed, students will be required to go through the Special Considerations procedures in order to request mitigation for that set. Please note that documentary evidence will normally be required before these can be considered. Referral Method: By examination, the final mark will be calculated both with and without the coursework assessment mark carried forward, and the higher result taken.
