Electric and Magnetic Fields
A reviewed 9814 repair guide for Electric and Magnetic Fields.
Before you begin
Use the diagnostic result to follow the H3 explanation, worked transfer, guided practice and independent practice before assessment and delayed re-test. H2 is tracked separately.
How the ideas connect
- Electrostatic equilibrium in conductors
- Gauss’s and Ampère’s laws
- Electric and magnetic dipoles

Lesson route
Objective clusters
- 01Electrostatic equilibrium in conductorsFree charge redistributes until the conductor is equipotential with zero internal field; surface charge produces a field normal to the surface.
- 02Gauss’s and Ampère’s lawsThe laws are general, but extracting a simple field requires a symmetry-matched surface or contour; closed-surface magnetic flux remains zero.
- 03Electric and magnetic dipolesDefine each dipole moment, then use its vector orientation for torque and potential energy; a uniform field can exert torque with zero net force.

Course coverage and review details
This standalone 9814 loop covers 9814 additional topic 3(a)–(i), PDF page 11. H2 Physics 9478 has its own separate course, examination and mastery record; optional H3 archive extensions are excluded.
Recorded selected-response work supports formative repair. It does not by itself prove constructed, diagrammatic or practical performance.
