Cobalt-based magnets have a higher saturation point and can also be used in high-temperature environments. Wind turbines, MRI machines, and hard disks are often manufactured with cobalt alloys. Graphite After comprehensive study and experiments, scientists have agreed that pure graphite can never be...
If we get lost in the woods, however, it’s likely we will have to be able to fend for ourselves, and being able to find true north may just help you in finding your way out. What is the Difference Between North and Magnetic North? Did you know there is a difference between true ...
Currently, one of the most promising concepts for the alternative energy sources is based on the conversion of the redundant electrical energy obtained from the sun, wind, etc., into elemental hydrogen to be used as an energy carrier. Conventional compression or liquefaction of hydrogen is ...
In contrast, an induction cooktop is convenient because, since there is no flame, it is not influenced by the wind [13,14]. Fourth, gas stoves can only be used when a gas pipe is installed; an induction cooktop has the advantage that it can be used wherever it is located [4]. ...
The northern lights give us a unique window into our sun's activity, space weather and Earth's magnetic field. At any given moment, the sun is ejecting charged particles from its corona, or upper atmosphere, creating the solar wind. When that wind slams into Earth's ionosphere, or upper ...

But as with wind and many forcesof nature, we cannot touch, feel, hear or see it.1. Which of the following is NOT TRUE about the earth'smagnetic field?A. It has no sound.B. It can't be seen.C. It surrounds the earth.D. It can be touched.2. How does the magnet hold the ...
Located in the Perseus cluster, the radio galaxy NGC 1265 is known as a "head-tail radio galaxy" because its lobes stretch out behind it, almost as if they are being swept back by a tremendous cosmic wind. The cause of this is theorized to be magnetic polarization in the tail. Radio ...
The Solar wind heads towards Earth All that material spewing from the sun spreads out into Space in all directions. A fraction of it will hit Earth, becoming entangled in our magnetic field. You may remember from school science classes taking a magnet and putting iron filings around it. Imagi...
