When introducing electromagnetism in schools, one specific experiment is inevitable: the force on a current-carrying conductor. Predicting the direction of the Lorentz force, the orientation of the magnetic field, and the direction of the electric current often causes difficulties for students. Here we present visual concept-relevant augmentations of the experiment that use the Microsoft HoloLens, which intends to counteract common students’ misconceptions by taking relevant principles of educational psychology into account.
Maxwell’s equations1 can completely describe the electrodynamics based on interaction of fields. Gauss’s law of a magnetic field B is Maxwell”s second equation for the magnetic flux:
It can be clearly interpreted as the fact that there are no magnetic monopoles and that magnetic field lines always form closed loops.
Maxwell’s fourth equation is formulated in the sense that an electric current I or a changing electric flux generates a...
