Yes, the effect penetrates through walls. The 70% or so of the people who can consistently feel the effect report being able to sense it passing through all materials, with one exception: lead. A thick (1/4" or more) sheet of lead seems to stop the "beam" from the device.
Nothing you come into contact with on a daily basis would cause problems (magnetic clasps on cellphone cases, etc...). For some larger magnets if there is a 2-axis compass it will not read correctly however it will have no effect on the GPS data or supporting electronics
I have two metal magnets crazy-glued to the bottom of my Garmin which when in use sticks to the two metal magnets I have hidden in my car's dashboard. I have been using it for years and they have not interfered with the signal.
Dont think so...
Some gps devices come with magnets at the base to be mounted on a metal object.
No, GPS uses microwave/radio signals which are unaffected by magnets.
The important reason to have a case for your GPS device is just in case you drop it. The case will prevent damage to your device. Also with a case you can keep the device and all the accessories (car mount and charger) in one place.
Yes, because it would help to decorate your freezer door. Magnets will not damage freezers, if that is what you are worried about.
The TomTom GPS has been rated high on many review websites. Using one is very easy, as the display, voice, and controls are clear and accessible. The only downside seems to be its mounting: it has been reported that it might damage the base or your car itself.
No, GPS accessories are not interchangeable between GPS brands. Each brand of GPS is made differently so you can not use Garmin accessory for you TomTom GPS.
No the magnet will have no impact on your phone
It might damage the floor, and it might damage the magnet.
It will damage them beyond repair
Yes, there is, but external magnets would damage the telephones if the magnet is strong enough. So don't go and try to place the telephone onto a neodymium magnet
yes. Microwaves, also, which have magnets are especially damaging. It also depends on the strength of the magnet and how close the object is to it and for how long.
No more than it damages your cellphone or smartphone.
If you take the car to a professional the gps can most likely be removed with no damage. However if you attempt to do it yourself you dash will most likely be damaged.
CD GPS systems can, in fact, be bought online. The only problem with buying them online, is installation. This can be difficult and may result in damage to the system if not handled properly.
If the temperature gets higher than a limit (I think it is called Curie temperature) then the fundamental pagentic dipoles loose their orientation and the magnet looses its magnetic field.
