Several people hate hard sciences like Math, Chemistry and Physics — especially Physics for it needs several months just to understand a simple concept like speed and vector analysis. Well, what most people do not know, and actually shy away from when encountered with such possibility, is that Physics can be real fun — if only one is determinedly attuned and willing to learning how Physics in the world works.
A group of students and professors alike from the University of Tel-Aviv’s School of Physics and Astronomy had put together an amazing and fun to watch demonstration of a Physics concept. The concept referred to here is the physics property of superconductivity, which if defined in a textbook like manner, is given the meaning of an event that the electrical resistance of some materials at a characteristically low temperature is at an exact zero electrical resistance.
In the video, an object can be seen as flying above a magnetic handset. The object, which is really a puck cooled off with nitrogen, creates a levitation effect between the magnet and the puck itself. This phenomenon is known as a MessenThe superconductor, levitates from a magnetic item because of the Meissner Effect, or a quantum locking between a magnet and a superconductor.
In quantum locking, the magnet can levitate above the superconductor and the superconductor can also levitate above the magnet. Since such event work both ways, this event too is considered to be an illustration of diamagnetism. Another fun thing in the video is the showcase of how the frozen puck floated above fast around a track force and later on floated below the track force. The levitation was definitely unbreakable unless someone had tried to get the puck out from the magnetic field of course.
Now, if only Physics subjects were taught through these examples in high school and even college, then surely no one else would be too scared to take the said science course. Unfortunately though, what are usually taught are theories, which is pretty understandable because Physics demands an understanding of the principle first before the application.
