FORCEFIELD will NOT be responsible for personal injury or property damage resulting from the use or misuse of our products! Please use caution and common sense, and please read and understand our safety warnings below!




Magnet Safety Warnings



Keep out of reach of children

Although magnets can be wonderful toys and highly educational, these are adult toys, and not for children. Small children should not be allowed to handle any of our magnets at all! Older children should handle them only under adult supervision, and wearing proper safety equipment (depending on the size and power of the magnets being used). Small magnets pose very little hazard, but large magnets should be handled with extreme caution.

Pacemakers and Defibrillators

Pacemakers and defibrillators can be sensitive to strong magnetic fields. If you or someone in your household has a pacemaker or defibrillator, or has health issues which require that you wear electronics of any sort, avoid magnets completely until you consult your doctor!

Pinch and Eye Hazard

Strong magnets can pose a serious pinch hazard due to their attractive force on each other and to any metal object containing iron. Usually surprise is an issue--they can jump out of your hands and snap together from a surprising distance before you realize what is happening. Though small magnets are quite safe, larger sizes are strong enough that they can pinch you like a pair of pliers, and be very difficult to remove from your fingers without help. They are strong enough that they can fly into each other or to a piece of iron or steel with such velocity that they can break and send sharp shrapnel flying about! Plus, your expensive magnets are then permanently broken.
ALWAYS use a strong grip and zen-like concentration when handling large magnets, and wear safety goggles. Some people wear gloves when handling them, this is at your option. Glove may help prevent accidental blood blisters if the magnets snap together, but they may also compromise you firm grip. Large magnets with sharp corners pinch and shatter the worst, rounded ones are safer. Small magnets are generally very safe.

Damage to magnetic storage media

Magnetic fields can cause damage to magnetic storage media. These include: cassette tapes, floppy disks, credit cards, video tapes, and computer hard drives. Keep all magnets at least 24 inches away from all types of magnetic media.

Damage to Electronics

Certain electronic devices are sensitive to magnetic fields and may be damaged permanently or temporarily disabled if exposed to a magnetic field that is too strong. Any video screen or television will become distorted and/or discolored if exposed to a strong magnetic field. While damaged screens can usually be demagnetized, its often tricky and may require qualified service technicians to do so. Other electronic devices like cellphones and pagers can also be damaged. Store your magnets in a safe place away from electronics of any kind.

Pregnant Women

Although there are no known health risks involving the handling of permanent magnets of the sizes we sell, just to be on the safe side we would advise pregnant women to avoid any exposure to strong magnetic fields.

Drilling and Machining

Neodymium magnets are by nature very hard and brittle. Although they can be cut, drilled and machined, it should ONLY be done by folks who are experienced with ceramics. If the magnets get over about 300 deg F, they will lose their magnetism permanently. They are flammable, and it is not difficult while grinding or machining to get them (or the chips and dusts from cutting) so hot hot they ignite. If they do ignite, the fumes are toxic and the material burns very fast and hot, like Magnesium! In our experience any machining of these magnets should be done with diamond tools under lots of coolant with good ventilation and the risk of fire in mind.

Shipping Magnets Safely

We take great care when shipping to see that any magnetic fields are well contained within the box we send them in. We pack very carefully so the external magnetic fields cancel out, and we use steel box liners as needed to insure that every box is safe and non-magnetic to comply with national and international postal regulations.


Electrical System Safety

While small electrical experiments and projects using small batteries are generally very safe, a large homemade alternator for a wind generator can make a lethal amount of electricity--as can a normal wall outlet in your house. A typical car battery can easily start a fire if shorted accidentally with a wrench. If you are unsure of the dangers involved with your particular project, consult with someone who is experienced. Always wear eye protection and gloves. FAILURE TO INITIATE AND FOLLOW YOUR OWN SAFETY PROCEDURES MAY RESULT IN BODILY INJURY OR DEATH! Possible hazards include high and low voltage electrocution, large items spinning very fast that could remove your head, high towers, power lines, battery acid, explosion danger from hydrogen or propane gas, and faulty wiring causing fires. IF YOU ARE NOT SURE, CONSULT WITH SOMEONE EXPERIENCED BEFORE STARTING!!!!!!

Science Experiment Safety

We offer several books that were originally published many years ago and have been reprinted. Some have CRAZY ideas in them, and no regard at all for what we would now consider prudent safety precautions. We offer these books because they explain in detail some wonderful projects and experiments which are difficult to find anywhere else. Some of them are downright dangerous! Although we have books which explain in detail how to build an X-ray machine, or a hang glider, we dont encourage it. These are fun books, full of excellent information - but please use common sense before taking on a project you found in a book which was originally published before the turn of the last century!
Some of these old books have excellent ideas for science fair and school projects that you rarely see anymore. Just be sure that an adult does some independant research, is supervising and does a safety check before allowing kids ot work on old science experiment ideas.


If you have concerns or questions about any of our products, please call or Email us before ordering. Common sense and good judgment should prevent any problems.
