Hi all, I am teaching an online course ( university level, 3rd year). My students are having a lot of difficulty visualizing the geomagnetic field, and making sense of how the declination/inclination changes spatially. Does anyone knows of good online visualization for the magnetic field of the Earth? 3D would be best, and interactive simulations would be ideal, but I might be wishing for the moon... you can email me your suggestions off list, I'll compile them and send a summary back to the list-serve. many thanks for your suggestions!
