This investigation describes and demonstrates a novel technique for the visualization of magnetic fields. Two ferrofluid Hele-Shaw cells have been constructed to facilitate the imaging of magnetic field lines. We deduce that magnetically induced photonic band gap arrays similar to electrostatic liquid crystal operation are responsible for the photographed images and seek to mathematically prove the images are of exact dipole nature. This is the last of the video series, the three/four...

Students who take UC San Diego's Physics of Surfing class get to go to beach, ride a board into the waves and see how physics works in the real world. Back in the classroom, they learn about how waves form, how they travel through the world’s oceans and that surfboards follow the laws of fluid mechanics.

We deduce that magnetically induced photonic band gap arrays similar to electrostatic liquid crystal operation are responsible for the photographed images and seek to mathematically prove the images are of exact dipole nature. This is the two magnet version with the non-pole sides...
