Lesson Plan: Magnetic Fields Physics
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to correctly draw the field lines of the magnetic field created by a magnet and relate field lines to the force experienced by two magnets.
Objectives
Students will be able to
- recognize and draw the field lines of the magnetic field produced by a bar magnet,
- recall that the arrows on the field lines of magnetic fields point from the north pole to the south pole,
- recall that the strength of the magnetic field is indicated by how close together the field lines are,
- recall that the magnetic field is generally stronger closer to the magnet,
- recall that if a compass is placed in a magnetic field, it will align to the field lines, with the north end pointing in the direction of the arrows,
- recall that two wide, flat magnets both aligned the same way will produce a roughly uniform field between them,
- recognize the shape of the magnetic field between two wide, flat, antialigned magnets,
- identify the orientation of a magnet given its field lines.
Prerequisites
Students should already be familiar with
- attraction and repulsion between magnets,
- forces.
Exclusions
Students will not cover
- magnetic fields generated by currents,
- field lines of a solenoid,
- calculation of the field strength of direction,
- how Earth produces its magnetic field.
