Magnetic Charger Make Apple Watch Levitated

We have seen hovering globe, or hovering potted plant already. But if there is a person said that Apple watch can levitate, we may think that is impossible. However, according to the reporter, there is someone have designed a battery charger, named Lift, that can make Apple watch charging with magnetic levitation. So in scientific world, nothing is impossible.


This Lift combined wireless charging with permanent magnet , to make your apple watch and the pebble smart watches levitate and charging in the air. The details of it like charging speed or charging time are not known yet. But the material is ceramic which has good conductivity, and the shell is made of aluminum alloy. What’s more, there is an inner battery in Lift, which can charge for our smart phone when it is in low battery, that is to say, Lift can also be a mobile power. But it is a pity that the smart phone can’t levitate.



Besides, when the Apple watch not in charging, the Lift can be a beautiful intelligent light. It can create soft light in any place with the intelligent bubble, called Orb.

The research team showed that they want to the Lift being a piece of museum art in the future, rather than a simple intelligent product. The charging device is being offered for $149 in the company’s Kickstarter. Do you want to have a try? It may not the most efficient means of charging, but it is absolutely the coolest.

PM Motor without Rare Earth Materials
UQM scientific technology company recently developed a permanent magnet motor without using rare earth magnetic materials. This motor mainly designed for EV and HEV. It is also applied for a patent named “brushless PM machine construction enabling low coercivity magnets”.

Since the motor magnets that made of rare earths have high corecivity, the electric motor of most EV and HEV in the market are permanent magnetic motor which of rare earths. The word corecivity is to describe the ability of resistance to demagnetization. And this time, the PM motor without rare earths designed by UQM was consists of AlNiCo and FeCoW, which make the motor has lower corecivity.

The new motor utilized a innovative geometric method, which can achieve higher magnetic flux destiny than old motor. And the low coercivity is also acceptable at the summit of magnetic flux destiny.

UMQ also showed that the new permanent magnetic motor provided a practicable plan based on our present technology of rare earths. Therefore, it can reduce the cost of rare earths. However, now we are still at the period of prototype designing, and if the test result of the first sample can meet our expectation, our program can get into next stage.

Ferrite Magnets Manufacturer China Rare Earth Magnet Limited
Recently, NDRC and NEA compiled and issued the plan of energy and technology innovation, which arranged 15 important tasks of grid technology, including wireless charging technology. On present, there are two main applications of wireless charging technology: electronics industry and the electric vehicle industry. Since 2015, Apple and Samsung have launched wireless charging phone, and the rise of electric automobile also create great market for wireless charging.

The advancement of wireless charging chain will help to boost the development of relevant material field. The main parts of wireless charging device are IC, the transmission coil, magnetic boards and modules, so the raw material ferrites of magnetic boards will benefit a lot. The wireless charging devices have some disadvantages of low charging efficiency and large heat, so to avoid these shortcomings, the main solution is to add magnetic boards on the transmitting end and the receiving end of the device. And ferrite magnets are the raw material of the magnetic board, it is a ferromagnetic metal oxide. Due to its high permeability when it is in high frequency, the ferrite has become nonmetallic magnetic materials in a wide range of a high-frequency weak field.

In accordance with the different placement of receiving end, wireless charging transmitter divided into fixed position type, single coil-free location and multiple coil-free location. And these transmitters require different ferrites. The first kind needs to neodymium-iron-boron permanent magnet sheet to make the receiving end in a fixed position, so that to achieve the maximum charging efficiency. The second kind needs high reliability of the magnetic board for the coil has to move, so it always uses flexible magnetic sheets. As for the third kind, it uses MnZn material of high Bs and low loss.

Permanent Magnets Become Batteries 20160801

Permanent Magnets Become Batteries 20160801
Magnet Manufacturer China Rare Earth Magnet Limited

Magnets become batteries and the bacteria can produce electricity.

Abstract: it is shocking that the researches have found that bacteria live on the tiny particles of the permanent magnets. They form into a group and can swallow and absorb the electrons. In recent years, this kind of bacteria has become a hot topic. Scientists have found that some bacteria form the deep sea and rivers can get electrons from the tiny metallic particles, through providing the electrons, iron particles become strong source for the effective power. Other kind of bacteria gets electrons through putting extra electrons to the metallic particles.



Nowadays, James Byrne and his colleagues from Tubingen university of Germany find that normal minerals ---tiny magnetite crystals can take the role of both the receiver and the provider of the electrons so as to work as batteries. He grow the bacillus sp. and the pseudomonas sp. bacteria on the permanent magnets and he finds that the bacillus sp is able to give the electrons to the crystals and the pseudomonas sp. Bacteria can get electrons from the crystals.
