Yes, the main risk to humans lies in the misuse of magnets. We see for sale on the internet incredibly large neodymium magnets that are sold to the general public.  These magnets are incredibly dangerous and can cause horrific injuries … nothing can prepare you for the devastation caused by two of these magnets attracting each other unexpectedly.  This is why we do not sell magnets above a certain size to the general public. If part of your body is caught between two attractive magnets then pinch injuries can be caused, the stronger the magnets the worst the injuries will be. As small neodymium magnets have been more widely available they can easily get into the wrong hands including children.  If swallowed these magnets can cause life-threatening injury and will require surgery to be removed. Heart pacemakers are also adversely affected by magnets and wears of such should not come into contact with magnets.
