 Pros and cons:

Pros:
-They can be used for variety of activities.
-Can be used in educational spaces.
-Children 14+ can use these magnets.
Cons:
-Swallowing ball magnets two or more of these magnets create a health risk. Since the small magnets are remarkably strong, they can attract one another even from some distance away. That means they can pull themselves together inside of you, breaking through bodily tissues to do so. Don’t leave them around animals, or children who don’t understand this.
-Low corrosion resistance. (If the plating is damaged)
-Will rust when exposed to wet elements.
-Brittle (May break, crack, or chip upon sudden collisions with other magnets or metals.)

    Applications of Neodymium Magnet:

    Acoustic field: the speaker, receiver, microphone, alarm, stage audio, car audio etc.
    Electronics: permanent magnetic actuator vacuum circuit breakers, magnetic relays, meter sound meter, a reed switch, sensors.
    Education: Teachers and researchers use magnet sets to model and explain physics, biology, and geometry concepts.

    Everyday life:   Can be a desk sculpture. You can pull them into a chain, fold them into a fabric, and meld them into limitless shapes: both abstract and geometric, flat or 3D. Use them when you need to massage your mind, practice your patience, relieve some boredom or alleviate some stress. Use tham to explain and teach children with visual shapes or movement created.

    Important warnings and tips for using magnets.

    Please make sure you read and take care when using magnets.

    How to separate magnets safely:
    To separate magnets, use a sliding motion, never try pulling magnets apart as it will cause them to snap together causing injuries. If you have larger stronger magnets use a wooden table or desk and overhang one magnet. Apply strong downward pressure to separate magnet from the other magnets. Once separated, keep moving the magnet to a safe distance.

    Magnets attract to each other handle with care:
    If two magnets are placed loosely apart, they could leap together unexpectedly, with extreme speed and force, which could shatter and break both the magnets and could injure your finger if it is caught in between. Flying chips are sharp and could be a danger to your eyes. Handle only one magnet at a time.

    Nickel Allergies:

    Some of our magnets have a nickle coating. Prolonged contact with skin may cause irritation.

    Warning for children using magnets:
    DO NOT allow children to play with magnets unsupervised and do not allow children to handle stronger magnets as they are powerful and will cause injury and could be fatal if swallowed. Magnets are not toys!

    Magnetic Sensitive Items:
    -Media: Keep away from credit cards and other magnetically stored media.
    -Pacemakers: Keep magnets away from pacemakers. The operation of heart pacemakers may be affected by the proximity of a magnet. Magnets can set a pacemaker working in a way that is not suitable for the user and that might affect their health.

    Liability:
    Magnet Store does not accept any responsibility for damaged caused by improper handling of these magnets. These magnets have a surprising amount of magnetic power and if handled incorrectly can be dangerous. With the purchase of these magnets, you confirm you have read and understood the following warnings. If you are giving magnets as a gift, please be sure to include this information sheet in the package.
