If you don't have a way to build a gaussmeter or magnetometer in order to measure the strength of the magnetic flux density of a magnet, then what else could you do? Try this. 1. Count how many paperclips or staples you can attach end to end from the north pole to the south ...
A compass needle isn't nearly as strong as many of the permanent magnets used today. But the physical process that magnetizes compass needles and chunks of neodymium alloy is essentially the same. It relies on microscopic regions known as magnetic domains, which are part of the physical structu...
At many universities, freshmen and transfer students are required to complete an online sexual assault prevention course before they arrive on campus. Some courses, includingthis oneused atMIT, include definitions of consent and coercion and explore the impact of alcohol. Other courses may cover...
When you realize that the Earth's magnetic field measures 0.5 gauss, you can see how powerful these magnets are. Most MRI systems use a superconducting magnet, which consists of many coils or windings of wire through which a current of electricity is passed, creating a magnetic field of up ...
Many parents looking at high school educational options are likely to encounter a magnet school, whether it is focused on science, the arts, public service or even more specialized interests. “Magnet schools have been a springboard for success for so many students,” says Todd Mann, executive...
Another common usage of neodymium magnets is attaching two magnets to each other to hang pictures on a wall and for many other applications. This is pull force case 3 and can also be found on all applicable product pages. Similarly to attaching magnets on a stainless steel surface like a re...
But all of these small steps combined have made this place a better place for getting around without so many cars. 6/15/2024: I rewrote the last paragraph after a better conclusion popped into my head not long after I woke up Saturday and added a little more explanation of Bike Angels....
Before getting to the final solution, I tried many other options that didn’t end up working out. First I tried the peel-and-stick magnets. They are nice because you don’t have to do any gluing and they are very thin. Too bad they are not strong enough to hold the containers to ...
Too many bloggers try to be cute. They hunt for an audience no one else is serving. They think: “If there’s no competition for this topic, creating a successful blog will be easy!” Wrong. If there are no competitors, who will link to you? Where will your audience come from? How...
Try not to casually mention it—dedicate at least a few minutes to catch as many listeners’ attention as possible. Add the affiliate link in the show notes: Your listeners may forget the name of the product you talked about by the time they get to the end of an episode. Make it easy...
