What are you viewing is strong magnet for flat battery and DIY projects. This Powerful Magnet is made of rare earth and nickel plating. This thickness of this strong magnet is 4mm, and diameter is 5mm. This Industrial Magnet is good to use with its strong magnetic function. This Industrial Magnet can be used at flat battery or used as lengthening. Powerful Magnet contains powerful magnetic force. You can toss them in the air to hear them, do tricks with your hands such as having one magnet on each side of a finger, you can chase one magnet along with the force of the other one. That makes them easier to stack into a cylinder than to connect side by side. The metal coating is durable, but Strong Magnet can chip or shatter. If used gently, these magnets can serve you for a lifetime. The Strong Magnet designed by our engineers is very ingenious and practical, this material has a durante and easy to clean surface. As our product has all the features of you need and is better compared with others. I strongly recommended it to you.

    How to measure how strong a magnet is

    Strong Magnet

    • The strength of a magnetic field is measured in units of mass / (electrical charge x time) and its standard unit of measure is the tesla (T). A tesla is defined as 1 kilogram / coulomb second and a gauss is equal to 0.0001 tesla. There are a variety of devices that measure magnetic fields, depending on the specific strength and type of magnetic field being measured. Scientific magnetometers that measure magnetic fields on Earth are typically extremely sensitive.

    Instructions: 

    • Examine the strength of some common magnets. The magnetic field of the Earth is about a half-gauss and a refrigerator magnet might have 100 gauss. The most powerful permanent magnet is based on neodymium and a small one may exert about 2,000 gauss. A large electromagnet can have a magnetic field of up to 15,000 gaussMeasure the force on the moment in a magnetic field with a capacitive cantilever beam magnetometer. These devices have a resolution of about 10^-10 joules per tesla (J/T) in a field of 0.1 T per centimeter.
    • Measure the magnetic moment in a very small sample with a piezoresistive cantilever magnetometer. These extremely sensitive magnetometers calculate the magnetic moment by measuring the changes in electrical resistance that occur hen the sample is bent.
    • Measure larger samples with a vibrating sample magnetometer. This device can measure samples up to 6 millimeters in diameter and has a resolution of 10^-6 J/T. A vibrating sample magnetometer can operate in a field of up to 33 tesla.
    • Measure magnetism on thin films, liquids and gasses with a magneto-optical Kerr effect probe. This device can function in magnetic fields of up to 20 T on samples that are up to two centimeters in diameter.

    Package Included:

    • 1 x Strong Magnet
