In my last article, I discussed the main types of magnetism and assured you to provide some more information regarding superconductors. Do have a look at ‘types of magnetism‘ to understand the concept of superconductivity.
WHAT ARE SUPERCONDUCTORS?:
As I told you in my previous article, superconductors show perfectly diamagnetic properties. Superconductivity is a phenomenon of exactly zero electrical resistance and expulsion of magnetic fields occurring in certain materials, called superconductors, when, cooled below a critical temperature. Though an ideal superconductor will have zero resistance at absolute temperature, however, achieving absolute temperature is itself not practical, what we can do is to get closer to it.
Since superconductor has the ability to repeal under the influence of the external magnetic field (discussed in ‘types of magnetism‘), people make exciting science experiments showing levitation and future transportation.
The main difference between normal diamagnetic materials and superconductors is that superconducting materials will have zero resistance while other diamagnetic materials will have resistance. Though, both of them will repel under the influence of the external magnetic field.
TYPES OF SUPERCONDUCTORS:
On the basis of the materials and critical temperatures, superconductors are divided as follows:
Type I-Superconductors: These are made of pure metals. When a material makes the transition from the normal to the superconducting state, it actively excludes magnetic fields from its interior; this is called the Meissner effect. The superconductivity exists only below their critical temperature (Tc) and critical magnetic field (Hc). Type I superconductors are well described by BCS theory, which is a bit advanced, thus will be described in my future posts.
Type II-Superconductors: These are made of alloys. Besides being mechanically harder than type I, they exhibit much higher critical magnetic fields (Hc). But they do not show the complete Meissner effect i.e. they do not exclude the magnetic fields completely, thus showing quantum locking/flux pinning. They are used for strong field superconducting magnets.
SUPERCONDUCTORS in 2019:
In one of my post titled, ‘amazing physics world 2019‘, I have unveiled the latest and upcoming research and experiments in the physics domain 2019. In that blog post, I also wrote about superconductors. In a nutshell, scientists are working to achieve superconductivity at room temperature. Many unsuccessful and almost successful attempts have been made and are being made to make a room temperature superconductor.
So what are your thoughts on such technology? Will it revolutionize our world? Give me your thoughts and theories on this topic down below. Do share this post with your friends and colleges and do read my other blog posts.
Woah! I’m really loving the template/theme of this site.
It’s simple, yet effective. A lot of times it’s challenging to get that
“perfect balance” between user friendliness and visual
appeal. I must say you have done a excellent job with this.
Additionally, the blog loads very quick for me on Firefox.
Superb Blog!
Thanks!
I really enjoy studying on this website , it holds great articles. “The secret of eternal youth is arrested development.” by Alice Roosevelt Longworth.
Good to see you find this article enjoyable. Do share it with your friends and colleagues.
My spouse and i got quite relieved when Michael managed to conclude his reports with the ideas he discovered from your very own web site. It’s not at all simplistic just to happen to be offering secrets and techniques which usually a number of people could have been selling. Therefore we take into account we now have you to be grateful to for this. All of the explanations you made, the straightforward site menu, the friendships you can aid to instill – it’s all astonishing, and it is aiding our son in addition to us consider that this subject is exciting, and that’s quite essential. Thank you for everything!
Your welcome ?
I simply needed to appreciate you once more. I do not know what I would have followed without the ideas shown by you over such situation. Previously it was a very challenging case for me, however , taking note of this skilled form you dealt with that forced me to cry over delight. Now i’m grateful for this help and in addition have high hopes you know what a powerful job your are carrying out instructing the rest using your webpage. I know that you haven’t encountered any of us.
Thanks so much for providing individuals with an extraordinarily terrific opportunity to read critical reviews from this website. It’s usually so pleasing and stuffed with a good time for me and my office acquaintances to visit your website on the least three times weekly to learn the latest things you have. And definitely, I’m always satisfied with the astounding principles served by you. Some 3 areas in this posting are clearly the most beneficial we’ve had.
A lot of thanks for every one of your work on this blog. Ellie enjoys setting aside time for research and it is obvious why. We all know all of the compelling mode you render priceless secrets by means of the blog and in addition strongly encourage response from other ones on that concern plus our favorite girl is truly starting to learn a lot. Have fun with the remaining portion of the year. You have been conducting a great job.
I really wanted to send a remark so as to appreciate you for the amazing steps you are giving on this website. My incredibly long internet search has at the end been paid with wonderful ideas to write about with my neighbours. I would mention that many of us visitors are very much endowed to live in a magnificent site with so many brilliant professionals with very helpful guidelines. I feel rather fortunate to have used your web page and look forward to so many more fun moments reading here. Thanks a lot once again for everything.
I simply wished to thank you so much yet again. I’m not certain the things that I might have created without the entire basics revealed by you regarding this area. It has been an absolute hard situation in my position, however , being able to view the well-written fashion you managed that forced me to cry over happiness. Now i’m grateful for this help as well as trust you are aware of a powerful job that you are putting in teaching people thru a site. Most probably you have never got to know any of us.
