Magnetism and induction
What students will learn
Distinguish magnetic sources from forces, then use changing flux and conservation to explain induction.
Before this topic
- Electric current and vector directions
- Circular motion and torque
- Circuit resistance, work, and power
Read and connect
Read: Magnetic Fields →
Read magnetic maps and connect material magnetism with dipoles, domains, and response to an external field.
Read: Magnetism and Moving Charges →
Keep a moving charge’s source field separate from its force in an external field.
Read: Magnetism and Current-Carrying Wires →
Map fields from currents and distinguish segment forces from a loop’s net force and torque.
Read: Electromagnetic Induction and Faraday’s Law →
Choose an area normal, track changing flux, and connect induced current with external mechanical energy.
Check understanding
Use the complete prompt to make student reasoning visible, then consult the separate worked reasoning and criteria. A reading completion tick records reading history.
Predict charged-particle directions and motion →
Derive the magnetic radius, draw force directions, and determine an electric field that balances the magnetic force.
Quantitative magnetic cases use perpendicular motion; oblique-angle comparisons remain qualitative and the motion model is nonrelativistic.
Account for energy in a moving-rod circuit →
Derive emf from area change and independently compare external mechanical power with resistor heating.
