How does Lane Assist know where the lane is? Lane Keep Assist is made possible by a camera sensor that is mounted behind the windshield in front of the rear-view mirror. The camera is able to detect lane lines on … Continue reading →

22-foot tall. The strongest magnet ever build is 22-foot tall and weights 34 tons. It was built in a research lab in Tallahassee and it produces a magnetic field of at least 45 Tesla. What is the biggest magnet on … Continue reading →

uru metal. Norse mythology and Marvel Comics tell us that Mjolnir is composed of “uru metal,” forged ages ago by the blacksmith Etri in the heart of a dying star. Presumably uru metal is magical in nature, and thus conveys … Continue reading →

The simple answer is, no, there is no shelf life; however, as all things go with magnets, it is not that simple. How long can a magnet last? Your permanent magnet should lose no more than 1% of its magnetic … Continue reading →

The world’s most powerful MRI scanner sits in the US National High Magnetic Field Laboratory. With an interior space just 10.5 centimetres in diameter, the 21.1-T machine is too small to be used on people. Schepkin and his colleagues there … Continue reading →

Radiologists at Massachusetts General Hospital, Boston have conducted the longest and most detailed MRI scan in history. By placing a brain into an MRI scanner for an impressive five days, they have managed to achieve a resolution as high as … Continue reading →

MRI is based on nuclear magnetic resonance (NMR), whose name comes from the interaction of certain atomic nuclei in the presence of an external magnetic field when exposed to radiofrequency (RF) electromagnetic waves of a specific resonance frequency. Is NMR … Continue reading →

Instead of high-cost Kevlar vests, researchers have discovered that armour made from traditional Thai silk offers similar levels of protection. Tests show that a speeding 9mm bullet can be stopped dead by just 16 thin layers of silk. Use of … Continue reading →

Open MRI sounds more comfortable and freeing. However due to their open structure the images are significantly degraded in terms of visible details, they are lower quality. Lower quality images can lead to misdiagnosis or the wrong treatment. Are open … Continue reading →

Magnetism is not felt by the human senses in any obvious way, nor is there any substantial evidence that it is harmful. Yet it does have subtle effects on vision and heart performance. Can magnetic fields harm humans? The Earth’s … Continue reading →

Yes. A magnetic field will produce eddy currents in a conductive (metal) projectile. These eddy currents will resist motion within the magnetic field with a force proportional to the square of the speed of the projectile. Can a bullet be … Continue reading →

A molecule called hemoglobin in the red blood cells contains iron.Because if magnets do attract blood, we must be careful of the magnets around us! Fortunately, the iron in our blood isn’t attracted to magnets. Iron is almost everywhere in … Continue reading →

The strong magnetic fields near neodymium magnets can damage magnetic media such as floppy disks, credit cards, magnetic I.D. cards, cassette tapes, video tapes or other such devices. They can also damage televisions, VCRs, computer monitors and CRT displays. Avoid … Continue reading →

Tesla coils produce a high voltage, but a low current in the human body. The current also wants to travel along the skin rather than through the major organs, so it will not hurt you, just pass through as long … Continue reading →

Musk received the Global Green 2006 product design award for his design of the Tesla Roadster, presented by Mikhail Gorbachev, and he also received the 2007 Index Design award for his design of the Tesla Roadster. Did Elon Musk design … Continue reading →
