Description:
The reciprocating electromagnet used in this product is a better magnet after repeated experiments, replacement and calculation. It can cooperate with hall sensor to generate magnetic force in a better position and achieve better operation effect. The bearing used is ball bearing with low friction and quiet durability, providing strong support for smooth operation. The product is supported by acrylic supports with high precision cutting on both sides, featuring high transparency, non-deformation and beautiful appearance. The beam supports are four carbon fiber columns, which are strong, durable and stable, showing the high-end atmosphere.
Features:
1. Low friction, quiet and durable
2. Multiple coils for choice
3. Comes with power adatper
4. Add LED design that lights up after turning on power, full of technology
5. Hall elements take the magnetic field as the working medium to transform the moving output of the object into the form output of digital voltage, which makes it have the function of sensor and switch.
Product Principle:
If the places a current(lv) in the conductor(d) in magnetic field (B), the direction of the magnetic field perpendicular to the direction of the applied voltage, then on the direction perpendicular to both applying current direction and magnetic field, it will produce another voltage (UH), which is called hall voltage. It's like a road, where people are evenly distributed on the road, moving forward, and when there's a magnetic field, they might wave away and go to the right of the road. Therefore, voltage difference will be generated on both sides of the road (conductor). This is called the hall effect. Hall element based on the hall effect, take the magnetic field as the working medium to transform the moving output of the object into the form output of digital voltage, which makes it have the function of sensor and switch.
Package Included:
1 x Multi Coil Car Engine V Model

Great Protective Case for My Mother’s iPad
Color: 2-Watermelon Red, Color: 2-Watermelon Red
I bought this case along with my mother’s new iPad, and it was the perfect choice. The watermelon red color looks beautiful with the pink iPad and gives it a very clean and stylish look. The case feels sturdy without adding too much weight, which makes it comfortable for her to carry around and use every day.
The stand feature works really well for watching videos, reading, and video calls. I also like that the case supports the auto wake and sleep function, which makes the iPad feel even more convenient and easy to use. The cutouts fit perfectly, and Touch ID still works without any issues.
The translucent back is a nice touch because it still lets the iPad color show through while keeping it protected from scratches and bumps. Overall, this case exceeded expectations and makes a great addition for anyone wanting both protection and style for their iPad.

Good product. What you see is what you get.
Color: 1-Navy Blue
Material feels sturdy and was a perfect fit compatible for my iPad. There's adequate grip and padding for a comfortable yet slim feel. Magnets hold it close and in one position when propping it up for watching landscape videos. Back is translucent as advertised. Solid product, put it on as i opened my new ipad for immediate protection. Perfectly safe blind buy if you're also getting that 'frequently bought together' suggestion from Amazon.

Bright & Pretty Hot Pink.
Color: Pitaya Red, Color: Pitaya Red
Very pretty and bright. It’s thick and great quality. Strong grip and doesn’t come off easily. Easy to clean when it gets dirty. It also has a nice backing. I prefer the transparent bright pink backing than the clear version. I love the strong magnetic for when I position it upwards. It can be positioned downwards too.
