a Magnet can damage an Ipad

MRI emits a magnetic field that rival the strength of the fields that make the Aurora Borealis. Bad news for most electronics.

Oddly enough I've done some reading on this and it seems a magnet, unless we are talking dangerously powerful, cannot erase flash memory.

However, I had to return an iPad that had failed and was assured by the 'Genius Bar' that they put them through a powerful magnet to erase the data. When I mentioned that magnetism doesn’t erase flash memory the response was "I'm not sure but that’s what they tell us to say"

A talk with Apple Support directly will probably be best for you. Residual magnetism can sometimes affect other magnetic field\inductive circuits leading to performance degradation. I am pretty sure the Apple technical people will have checked the possibilities out during the design process. Be aware that magnets are used in the Magic cover that attaches to the top of an ipad and can be used to turn it on/off. Since the chassis should be grounded and the shields underneath are built to protect the circuitry from stray interference I would have said the answer is no. But a call to technical support may be best to put your mind at ease. There should also be a warning with the idevice documentation (usually at the back) about exposure to certain conditions.

only old harddisks that use magnetic storage of data could in theory be affected by a passive earth magnet is far from strong enough

Given that there are magnets built into the iPad and magnets in the Smart Cover, I'm pretty certain the answer is "No". However, if you took a big enough magnet and dropped it on the iPad, it would damage it.

Since the drives are solid state, very unlikely, unless you drop it on the iPad 😁.

I,suppose it is possible if we are talking about a very strong magnetic field, and electromagnet for example, but even then I doubt it.

I tool a magnet that can hold a 110kg and rubbed it all over my iPad. It no effect whatsoever besides sticking to it in csertain plces.

Many iPad accessories are designed with and use magnets including Apple's cases and covers. Event in the days of cassette and video tapes it took a very strong industrial magnetic field to erase data. The magnetic field of almost all magnetic devices available to consumers will not hurt magnetically stored mediums. Even my wallet has a magnetic clasp which has never effected my debit and credit cards.

Oh, my ... I guess I don't know what I thought the field strength of an MRI machine was, but that sounds a little dangerous ... if I ever have to get in one, I will be sure to leave my iPad and phone in the car ...

A bit of an exaggeration, but using an active MRI donut for a target while throwing your credit cards around is not a good idea.
