Stark 5v 6w Power V-shape Electromotor Model High Speed Electromagnet Car Engine of 12 Coil - Coil Random ColorFeatures:
.V-shaped design, 12 coils, excellent stability, explosive force and dynamic explosion, exposed operation, polished after clear acrylic cutting, exquisite bottom plate, principle display and look and feel are excellent, showing an unusual taste of a person
.The input voltage requirement of the product is small, the voltage of 5v can be used, the mobile power supply can be activated, and the product is ready to be loaded, no need to reassemble, and it is extremely convenient
.Product Description: The reciprocating electromagnet used in this product is the best magnet obtained after many tests, replacements and calculations. Hall sensor cooperate, can generate magnetic force in a good position, and the best operation effect is achieved,the operation effect is the best. The bearing used is a ball bearing, which has the advantages of low friction, quietness and durability, and provides strong support for smoother operation. The high-quality cutting acrylic support is used on both sides of the product, which has high transparency and no deformed, beautiful appearance, the beam bracket is four carbon fiber columns, durable and stable, showing the high-end atmosphere
.Product Principle: If a current (Iv) is applied to a conductor (d) located in a magnetic field (B),the direction of the magnetic field is perpendicular to the direction of the applied voltage. Then another voltage (UH) will be generated in the direction perpendicular to both the magnetic field and the direction perpendicular to the applied current. People call this voltage hall voltage,this phenomenon is known as the hall effect.Like a road, where everyone is evenly distributed on the road, moving forward.When there is a magnetic field, people may be pushed to the right of the road.Therefore, on both sides of the circuit (conductor), a voltage difference will be generated.This is called the hall effect.According to the Hall effect, the Hall device uses the magnetic field as the working medium to convert the motion output of the object into a digital voltage output, so that it has the functions of sensing and switching. The multi-cylinder engine has two or more cylinder engines, which are composed of several identical single-cylinders arranged on one body and share the root crankshaft output power
.The product is suitable for people over 8 years old. The product is suitable for teaching models, technology decoration, gift giving, DIY modification, etc.

Lovely Slate Gray Jewelry Box
I just received this Slate Gray jewelry box. It's really quite lovely and just the right size for my granddaughter's vanity. I'm really excited about giving it to her, for her 12th Birthday, to hold her better jewelry. It's so nice I'm going to order another one for my other Granddaughter's Birthday.

Songmics Slate Gray Travel Jewelry Box
I purchased the slate gray Songmics jewelry box for travel purposes. We take long vacations and have an upcoming 20 day cruise. I wanted a jewelry box that was compact enough to put in my carry-on bag, but still had room to hold a months worth of jewelry, especially to keep my necklaces for tangling. When this arrived, I was pleasantly surprised and the packaging was great, shipped in a sturdy box. so no damage to the jewelry box. The color is a rich gray and the 2 tier box, while small, holds a lot of jewelry. I wanted to purchase the ink black but could not justify paying twice the price of the gray one just to get it in black. It is small enough that it will fit in most any hotel/ship safe so I won't be sitting out in the room anyway. It has a strong magnetic snap that keeps the box from opening while in transit. The one negative for me is that the pierced earring card is so thick that my earrings barely go through to have enough room on the back side the slip the backs on. I may separate the double thick card, realizing it will not look as nice but will be more functional. The bottom half of the box will hold bracelets up to 1 1/4" wide. There is enough room under the earrings card to place pendants, additional earrings, etc. The necklace holder is designed to hold 5 necklaces, but I added one more by going across the top, end to end, to prevent tangling. I also placed smaller hoop earrings in the ring holder which holds them securely. This box held 7 bracelets, 2 of which were wide, 5 rings, 9 necklaces (I placed 3 in the bottom of the box, and had room for 23 pair of earrings (some placed in the ring holder and in the bottom of the bo)! I would buy this again in a heartbeat.
