T2mm2) are considered appropriate to ensure, with a safety margin, that powerful magnets of this type will not
be permitted for use in toys if they fit entirely within the small parts cylinder. By introducing the flux index limit,
the risk of injuries with magnets will be minimized. As additional data becomes available in the future, this limit

Two or more magnets can attract each other and form a compound magnet with a higher flux index than each
single magnet. The flux index will not double if two equally strong magnets are attracted to each other and the

magnets released from electrical or electronic components.
