There is nothing in an iPad that will be effected by a magnet, as it has:
- SOLID FLASH MEMORY (doesn’t contain anything magnetic inside and therefore it would be immune to the magnetic influences;
- LED screen (they do not use a beam or phosphors but static liquid crystals, which are solid-state unmoving cells, and so they are immune to magnetic influences);
It's an urban myth that magnets effect electronics: Commercial computer recycling firms use devices called "degaussers" as an easy way to wipe hard drives. Theses are huge electro magnets but even still they do not damage the computer but just wipe the hard drive contents (not the SOLID FLASH MEMORY as memory cards, USB thumb drives, solid state drives)
Magnets, they also have a very short range of attraction:
Magnetic field intensity decreases as the square of the distance between the objects. Increasing the distance between a small, powerful magnet and an iPad by a factor of ten (from 1/10 inch to one inch) decreases the field strength by one hundred times.
Using the ARM, the iPad is shielded from the magnets by a thin layer of silicon and iron: this small distance makes the magnetic influence close to zero.
So the Magnets are not a problem for iPads: Apple themselves would not came with the SMART COVER (which contains magnets strong enough to hold the iPad by the Cover itself) and would not put 10 Magnets right into the iPad.
We have been testing and using our Magnet mount system in the last 5 months (we left the iPad attached to very strong magnets days and nights) without any issue at all.
