What is Electromagnet and it's Applications?

Welcone back friends in the World of Why and How with your host - Science Cinch . Today we will see some astonishing characteristics and use of electromagnets. Let's begin! Most of us noticed that, a compass needle usually point North & South directions, if there are no other magnets near it. But, if there are magnets near compass, the needle will be attracted towards them and will point in a different direction or be deflected. Similarly, if a compass was held near a wire carrying an electric current, the needle was deflected. But if the current was switched off the needle swung back and pointed North-South again. This meant that the current passing through the wire produces a magnetic field. This is Ampere's law, which states that the magnetic field created by an electric current is proportional to the size of that electric current, with a constant of proportionality equal to the permeability of free space. Electromagnets uses this concept, usually an electromagnet consis...

Why we can not hear sound in Space?

Sound waves are machanical waves. Sound is produced in the form of a pressure wave. When an object vibrates, it causes the surrounding air molecules to vibrate, initiating a chain reaction of sound wave vibrations throughout the medium. So, in order for sound to travel, there has to be something with molecules for it to travel through. On Earth, sound waves travels to your ears by vibrating air molecules but in deep space, the large empty areas between stars and planets, there are no molecules to vibrate. So, there is no sound there.

Hello everyone, most of us specially students are complaining about the lack of concentration, specially about their inability to complete scheduled study time table. There are many reasons for this phenomenon in general, if we will going to discuss those; but here we are trying to provide a solution with taking minimum time of yours. So, let's directly focused on method and solution. This method is call , 10 Minutes Focus Theory for Controlling Mind , basically I started this method on myself some time back and I found good results from this. That's why I am sharing this with all of you on my blog.  In this method, when you are bored or lost interest from work or study, you should have to take extra 10 minute time for ending work,  reading or studying or something else. You have to say to yourself that,  ' I am taking these LAST 10 Minutes and after that I stop doing this work, but in these 10 minutes, I must give my 101%; so, I have to forget whole World for ONLY these...
