Project 1: The Physics of electric motors Overview The working of the electric motor is based on three principles:  `

• Moving charges produce magnetic fields.
• A single charge or conductor with moving charges experiences a magnetic force when

placed in an external magnetic field.

• Conservation of energy

Content

1. Introduction

2. Short discussion of the three principles.

3. Discuss how these principles are applied in the electric motor.

4. Summary/Conclusion
