A magnetic field of 1 T (N/A*m) field strength is a very strong field found only in powerful electromagnets. Fundamentals of Resistive Magnets, National High Magnetic Field Laboratory, Florida State University. “Junkyard magnets used to pick up old cars produce … Continue reading →

How long does a permanent magnet last? A permanent magnet, if kept and used in optimum working conditions, will keep its magnetism for years and years. For example, it is estimated that a neodymium magnet loses approximately 5% of its … Continue reading →

First of all, the Iron Nitride is more powerful than Neodymium magnet (Neodymium magnet). The costs of Nitrogen and Iron are very low compared to rare earth magnets. It is possible to produce Iron Nitride Magnet with production techniques currently … Continue reading →

The unit is part of the Gaussian system of units, which inherited it from the older CGS-EMU system. It was named after the German mathematician and physicist Carl Friedrich Gauss in 1936. One gauss is defined as one maxwell per … Continue reading →

At this rate of decrease, the field would be negligible in about 1600 years. However, this strength is about average for the last 7 thousand years, and the current rate of change is not unusual. Will the Earth’s magnetic field … Continue reading →

Lighting a bulb with just a magnet is not possible but if you have a conductor besides a magnetic field and if you can create a flux linkage to produce a dc current, you can surely light a bulb. How … Continue reading →

1 N is the force of Earth’s gravity on a mass of about 102 g. On the Earth’s surface, a mass of 1 kg pushes on its support with an average force of 9.8 N. 1 Newton is equal to … Continue reading →

The first magnets were not invented, but rather were found from a naturally occurring mineral called magnetite. Traditionally, the ancient Greeks were the discoverers of magnetite. There is a story about a shepherd named Magnes whose shoe nails stuck to … Continue reading →

The new high-field open MRI at Insight Imaging – West Thunderbird is the most advanced open MRI system on the market today, with a magnet strength comparable to traditional high-field units. Are there any open MRI machines? Open MRI machines … Continue reading →

This is because the iron in our blood isn’t made of extra small metallic filings of the element.But because most of the blood in our bodies is made up of water (which is also diamagnetic) and oxygenated hemoglobin, our blood … Continue reading →

To charge an electric car, you’ll need to plug it into a charging point.Sometimes drivers need to charge en route, using higher powered chargers. Depending on the location, you can start charging simply by plugging in, or by using an … Continue reading →

But here’s where things start to get dicey: The approximate amount of lithium on earth is between 30 and 90 million tons. That means we’ll will run out eventually, but we’re not sure when. PV Magazine states it could be … Continue reading →

Magnetic levitation is commonly referred to as MagLev.He said: “The classic way of doing magnetic levitation is using magnets. Take two magnets, or a magnet and a piece of superconductor, which will then have opposing magnetic fields.” The repelling force … Continue reading →

As of January 2017, many brands of magnet spheres including Zen Magnets have resumed the sale of small neodymium magnet spheres following a successful appeal by Zen Magnets in the Tenth Circuit US Court of Appeals which vacated the 2012 … Continue reading →

It’s true that some people have stickier skin than others, and are quite capable of temporarily attaching massive, macroscopic metallic or magnetic objects to their bare skin. But it isn’t because they’re magnetic; the human body generates and possesses no … Continue reading →
