Crime-Stopping Magnets

Crime-Stopping Magnets - We’ve all been there -- you just finished shopping, you’re tired from a long day, and then the annoying alarm goes off just as you try to leave the store. But have you ever wondered how it works? Well, if a little white strip attached to your item or tag is what [...]

Magnetic Energy

Magnetic Energy - What if you walked out of your house and entered the car of the future, which looked like a donut? You push a button and the vehicle rises about a foot from the ground. A small thruster moves the vehicle forward as the vehicle follows an electromagnetic strip embedded in the road [...]

Modern Permanent Magnets

Modern permanent magnets are far removed from the traditional horseshoe magnets. Today, magnets are available in a variety of shapes to suit many applications, and the introduction of magnetic alloys and magnetic-oxide based ceramics has made the simple iron magnets the exception rather than the rule. Modern permanent magnets Advances in magnet technology [...]

How Speakers Work

How Speakers Work - Making Sound: Speaker Magnets When the electrical current flowing through the voice coil changes direction, the coil's polar orientation reverses. This changes the magnetic forces between the voice coil and the permanent magnet, moving the coil and attached diaphragm back and forth. How Speakers Work So how does the [...]

Do permanent magnets have a half-life or otherwise “decay” over time?

Do permanent magnets have a half-life or otherwise “decay” over time? from reddit Physics It seems like there must be some energetic cost to constantly exerting a force on the surroundings. As particles & objects resist that force, it must exert some backward torque or whatever on the aligned atoms of the magnet. Over time, [...]

Permanent Magnet Stability

Permanent Magnet Stability Permanent Magnet Stability - The ability of a permanent magnet to support an external magnetic field results from small magnetic domains "locked" in position by crystal anisotropy within the magnet material. Once established by initial magnetization, these positions are held until acted upon by forces exceeding those that lock the domains. The [...]
