Neodymium magnet safety

A short video on how to use neodymium magnets safely. Aimed at teachers in secondary schools, teaching GCSE or A level physics or equivalent level qualifications (exams taken at age 16 and 18).
WARNING
Neodymium magnets are dangerous. Ensure you are careful when using them, and give sufficient warnings to students.
● Keep them away from pacemakers, watches, phones, calculators, computers, screens/TVs, tablets, credit cards, USB memory sticks, hard drives, and other devices that can be damaged by magnetic fields.
● Two magnets in close proximity can come together very quickly and with a large amount of force. Fingers and other body parts can be ‘nipped’ quite painfully, and cause injury.
● Magnets should never be swallowed or placed in mouths, up noses, etc. Two magnets, or one magnet and an object that is attracted to it, can pinch internal organs, such as the gut or the nasal septum. This can cause internal bleeding, which can be fatal, and it will require surgery to remove them.
● Magnets coming together can chip, break or shatter, causing sharp splinters. These small pieces of magnet can easily be missed, and can cause further damage / injury.
● Neodymium magnets are often coated with nickel, which can cause allergic reactions.
Always make a risk assessment and follow your organisation's guidelines for using strong magnets.
Teachers - if allowing students to handle magnets, count them all out and count them back in again! These are very tempting items!
If you use neodymium magnets or other strong magnets it is your own choice to do so and you use them at your own risk. Richard Grimmer does not advise you to use neodymium magnets. He accepts no liability for any loss, injury, damage to property, or other adverse effects to you or to anyone else with whom you use any magnets.
