Lesson Plan: The Magnetic Field due to a Current in a Solenoid Physics
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to calculate the magnetic field produced by a current in a solenoid.
Students will be able to
- use to find the magnetic field strength at the center of a solenoid,
- use for the same results,
- identify from a diagram of a current-carrying solenoid which way the magnetic field at different points around the solenoid points.
Students should already be familiar with
- the idea that current-carrying wires produce magnetic fields,
- the shape of the magnetic field produced by a single loop of current-carrying wire.
Students will not cover
- other geometries: straight wire, rectangular wire, and single circular loop,
- the vector forms of this formula,
- the magnetic field produced by time-varying currents,
- electromagnetic induction,
