For people who are always on the go, carrying a phone charger in addition to a cell phone is probably a common practice. The battery life of most cell phones just can’t keep up with real life. But instead of searching for a free outlet at a coffee shop, some power companies created wireless chargers that use magnetic force instead of cords to transfer power. Continue reading →
You probably know that fridges and certain metals are attracted to magnets. However, there are some surprising items that you may never have guessed are magnetic. In this blog, we are taking a look at some everyday items that can actually have magnetic properties. Continue reading →
Did you know that many experts say that there is a shortage of helium? The U.S. has been the biggest supplier of liquid for some time and the National Helium Reserve houses a majority of the Earth’s helium. As the abundance of helium depletes though, some scientists are worried about how the growing demand and limited supply will affect us. According to recent reports, the demand for helium is expected to increase 2 to 3 percent as industries like electronics and healthcare increase their usage of it. Continue reading →
Magnets come in a variety of shapes and sizes like disc, sphere, horseshoe and a number of other unique forms. Usually, bigger magnets are stronger, but now always. Small magnets can be improved to increase strength by using different materials. The shape of a magnet, however, can tell you a lot more than size. Each magnet’s shape has an influence how it is used. It determines how the magnetic field lines are arranged outside of the magnet as well as the strength of its pull. What are some of the common shapes of magnets and how are they used? Continue reading →
Does your home have a doorbell installed? If so, we bet there is a magnet inside of it. If you take a doorbell apart, you’ll likely see a magnet and some copper or other conducting wire. If you know a little bit about electromagnetism, you’ll recognize that the setup of a doorbell is based on it. Here’s how it works: Continue reading →
Magnetic shielding may seem like the stuff of science fiction novels and movies, but it’s real. Unlike some forces, such as electricity, magnetic fields can’t technically be blocked. This is because there is no monopole magnet--or at least not one that we know. The magnetic field lines run from a magnet’s north and south pole, which makes blocking them difficult. Continue reading →
Do you know that the most powerful magnets in the universe are actually a type of star. Magnetars are the remains of stars that have “run out of fuel”, or in other words, hydrogen. The star is essentially dying, and when this happens, it tries to compensate for the lack of fuel by burning all the types of elements. This smorgasbord of fuels causes the star to burn as a bright red giant, but only for a temporary time. Eventually, the burning causes the star to burst into a supernova explosion. Continue reading →
Some would argue that magnetic resonance imaging (MRI) machines have become as essential to the medical field as blood tests when it comes to diagnosing and treating patients. MRIs allow doctors to see inside the human body non-invasively. A physician named Raymond Damadian and not an engineer was actually the inventor of the earliest MRI model. Recently, MRIs have even been used to guide ultrasound waves in Alzheimer’s treatment.
You may already know that magnets are used in magnetic resonance imaging machines, but do you know what types of magnets are used or how it works? In this blog, we are taking a look at how the magnets in MRIs allow us to see inside the human body. Continue reading →
Magnets are interesting and strange materials. There are still some mysteries that scientists and researchers have yet to solve when it comes to magnets. However, some mysteries have been solved. In this blog, we have compiled a list of some of the strangest facts about magnets and magnetism. Continue reading →
Superconducting magnets are used in MRIs, Maglev trains, particle accelerators and other technologies that often use magnetism and high power conditions to operate. What are superconducting magnets? First, in order to understand what superconducting magnets are we should discuss superconductors and electromagnets. Continue reading →
