Guidelines for safe use of NdFeB disc magnets

1. Avoid being pinched by magnets
The magnetic force of NdFeB disc magnets is very strong. When two magnets attract each other, they generate a great adsorption force at the moment of approach. If fingers or skin are caught between magnets, they are easily clamped by force, causing skin squeezing, bruising, or even skin breakage. This risk is especially high when large-sized or multiple magnets are stacked.
Recommendations:
Use tools instead of direct contact with hands during operation, or wear thick gloves.
Keep a certain distance between magnets to avoid accidental approach.
Do not let magnets collide suddenly, approach slowly to control the suction force.

2. Stay away from electronic devices and storage media
The strong magnetic field generated by NdFeB magnets can affect surrounding electronic devices and magnetic storage media. It can cause hard disk data loss, demagnetization of credit card magnetic stripes, and even interfere with the normal operation of medical devices such as pacemakers.
Specific impacts:
The magnetic heads and data structures in data devices such as hard disks and USB flash drives are easily damaged.
Magnetic stripe information on credit cards, bus cards, etc. may be erased.
Electronic timers, mobile phones, and computers may malfunction.
There are serious health risks for people wearing pacemakers or other implanted medical devices.
Recommendation:
Stay away from the above devices when operating magnets, and keep a safe distance of at least tens of centimeters.
Patients with medical devices should avoid exposure to strong magnetic fields.

3. Avoid swallowing risks
NdFeB magnets are small in size and have extremely strong magnetic force. Swallowing them by mistake can cause serious harm. Multiple magnets will attract each other in the intestines, which may cause intestinal perforation and obstruction, and in severe cases require emergency surgery.
Pay special attention to:
Children and pets are very likely to swallow small magnets by mistake.
Adults should also prevent magnets from falling off and accidentally entering their mouths when operating or playing.
Recommendation:
Keep magnets out of reach of children and pets.
Do not put magnets in pockets or near the mouth.

Educate family members, especially children, to recognize the dangers of magnets.

4. Wear appropriate protective equipment
NdFeB magnets may be quickly adsorbed or splashed when operating, causing hand or eye injuries. Wearing protective equipment can greatly reduce the risk of accidental injury.
Recommended equipment:

Protective gloves: reduce the risk of fingers being pinched and enhance grip.

Goggles or safety glasses: prevent magnet fragments or debris from injuring the eyes.

Long-sleeved work clothes: protect arms and other parts of the body.

5. Avoid collision and fragmentation of magnets
NdFeB materials are brittle in nature. Strong impacts may cause magnets to crack or shatter, and sharp fragments can easily scratch the skin. The performance of the magnets after shattering will also decrease.
Recommendations:

Handle magnets with care and avoid dropping them from heights.

Do not strike metal or other hard objects with magnets.

Use cushioning materials such as foam or cloth wrapping when storing.

6. Storage recommendations
When magnets are not in use, proper storage can prevent magnetic force loss, corrosion and accidental adsorption.
Storage tips:

Keep in a dry environment to prevent rust, especially for magnets that are not protected by coatings.

Avoid high temperature environments (generally not more than 80°C), which can cause magnetic properties to decrease.

Use a dedicated isolation plate or magnetic storage box to prevent damage caused by magnets adsorbing each other.

Avoid placing near magnetically sensitive items.
