ELECTROMAGNETISM
Magnetic Induction, Inductance, AC and LC Circuits
K-12 Standards
Upon successful completion of this module, students should be able to perform the following:
-
Identify the factors that affect the magnitude of the induced emf and the magnitude and direction of the induced current (Faraday’s Law)
-
Relate Faraday’s experiments and Maxwell’s evaluation to a given experiment
-
Compare and contrast electrostatic electric field and nonelectrostatic or induced electric field
-
Calculate the induced emf in a closed loop due to a time-varying magnetic flux using Faraday’s Law
-
Describe the direction of the induced electric field, magnetic field, and current on a conducting/nonconducting loop using Lenz’s Law
-
Compare and contrast alternating current (AC) and direct current (DC)
-
Use analogies with the spring-mass system to draw conclusions about the properties of LC circuits
-
Characterize the properties (stored energy and time-dependence of charges, currents, and voltages) of an LC circuit
-
Perform demonstrations involving magnetic induction in contexts such as, but not limited to, power generation, transformers, radio tuning, magnet falling in a copper pipe, and jumping rings.
