Is is safe to use magnets on a case for the J3?

[briant1234]

hi, im currently creating a case for my gorgeous J3. I want to create a flap to close the case, but is it safe to use a magnet to hold the flap shut? Would it affect the J3's memory or anything? (The general rule of thumb that i learned for electronics, is not to place magnets near them. Will this apply to the J3?)
