Question

2 identical bars are ( steel and magnet ) painted with the same colour . How can we find the magnetic bar by using only those 2 bars ? ( " SHOULDN'T TRY TO BREAK THE BARS " )

Answer 1

Touch the end of one bar (A) to the middle of the other bar (B) forming a 'T' shape. If the bars are attracted then bar A is magnetized and if they are not attracted then bar B is the magnet. This is because magnets have fields at the poles (the ends) but not in the middle. So the end would attract and middle would not.
