Calculate forces on current-carrying wires, understand torque on current loops, and analyze the basic electric motor.

Use the Biot-Savart law concepts and Ampere's law to find fields from wires, loops, and solenoids.

Calculate magnetic flux through surfaces and understand how flux changes with field strength, area, and orientation.

Apply Faraday's law to calculate induced EMF and use Lenz's law to determine the direction of induced currents.

Analyze how generators convert mechanical energy to electrical energy and how transformers change voltage levels.

Understand how Maxwell unified electricity and magnetism, predicted electromagnetic waves, and identified light as an EM wave.
