Learning Outcomes
When you have completed this chapter, you will be able to:
Knowledge
define electric current as the amount of charge passing a reference point per unit of time
describe magnetic interactions in terms of forces and fields
compare gravitational, electric, and magnetic fields
describe how the work of Oersted and Faraday led to the theory relating electricity to magnetism
describe a moving charge as the source of a magnetic field and predict the field’s orientation
explain how uniform magnetic and electric fields affect a moving charge
describe and explain the interaction between a magnetic field and a moving charge and a conductor
explain, quantitatively, the effect of an external magnetic field on a current-carrying conductor
describe the effects of moving a conductor in an external magnetic field in terms of moving charges
Science, Technology, and Society
explain that concepts, models, and theories are often used in interpreting, explaining, and predicting observations
explain that technology provides solutions to practical problems explain that scientific knowledge may lead to the development of new technologies and vice versa
