DETERMINING THE VELOCITY AND MAGNETIC FIELD DEPENDENCE ON THE MAGNETIC FRICTION AND TERMINAL VELOCITY OF THE MAGNETS MOVING ON A CONDUCTOR

  • Researched under the mentorship of Dr. Hee Tae Jung, professor at the Physics Department at Gaheon University

  • Analyzed the magnetic dipole-dipole interaction at differing magnitudes, distance dependence, dipole moment, etc. 

  • Compared the experimental data to renowned theory and drew an empirical relationship to better understand the change in magnetic force according to a change in the change of the number of magnets and distance between the two magnets.

STUDYING THE RELATION BETWEEN THE VAMPIRE SQUID MORPHOLOGY ON THEIR LOCOMOTION

  • Researched under the mentorship of Dr. Trevor Gonzalinajec at UC Berkeley Biomechanics Department and Bioengineering Department, Stanford University

  • Designed and researched the method of measuring the locomotion efficiency of vampire squid's web between tentacles by analyzing drag force and current generation.

DETERMINING THE BRIGHTEST WAVELENGTH OF LIGHT IN SEAWATER

  • Researched under the mentorship of Jeon Dong Lyeol of Seoul National University's Physics Department

  • 2nd place winning project @ 2016 Seoul National University Invention Convention

  • Created a simulation of a person stuck in the sea requesting help using light on their life jacket in order to distinguish what type of light is the most efficient in detecting from a distance under the mentorship of Dr. Jeong from the Physics Department, Seoul National University.

 

DETERMINING THE VELOCITY AND MAGNETIC FIELD DEPENDENCE ON THE MAGNETIC FRICTION AND TERMINAL VELOCITY OF THE MAGNETS MOVING ON A CONDUCTOR

The velocity dependence on the magnetic friction and the magnetic field dependence on the terminal velocity of the magnets moving on the conductor plane were investigated. Amechanicalfriction effectwas eliminated by attaching the magnet to a cart which moves almost frictionless on the plane. From the relation between the terminal velocity and acceleration of the cart, themagnetic friction acting on the cart was found to be linearly dependent on the velocity. The magnetic field dependence on the terminal velocity was also investigated under the various magnetic fields and fixed acceleration. The terminal velocity of moving cart decreases linearly with respect to the increasing relative magnetic field intensity.

 

STUDYING THE RELATION BETWEEN THE VAMPIRE SQUID MORPHOLOGY ON THEIR LOCOMOTION

The deep ocean remain unexplored, and as a result, the organisms dwelling within the waters are also an unsolved mystery. Though the vampire squid was discovered during the 20th century, there are sill many questions surrounding its peculiar morphology. Our hypothesis is that the unique webbing characteristic of vampire squid contributes to more efficient locomotion. For further research, we would like to explore whether the connective tissue has further advantages besides locomotion, given the abnormal degrees of temperature and high pressure that a vampire squid lives in. As a result, it is apparent from the experiments that the vampire squid produced the most drag due to the presence of the connective tissue between the tentacles and therefore is the least effective in locomotion. However, when both the vampire and the standard squid are in a closed position, they both generated same drag force.
