Can you solve the MAGNET RIDDLE? ft YouTube CEO Susan Wojcicki

It's been a while since I played with rectangular magnets, but it should be pretty simple without breaking anything. One is a permanent magnet, and the other becomes temporarily magnetised when the permanent magnet comes close. For a permanent magnet, the magnetic field is strongest at the poles and weakest in the middle, whereas the temporary magnet has poles always facing towards the poles of the other one. The upshot is, you hold them both tight, and bring them close in three different different configurations to determine which is the temporary magnet.

First, bring them together and let them attract each other and stick to each other; you are guaranteed that the pole of one is on one of the faces of the magnets. Then pull them apart slightly, holding tight. First, rotate the left one 90 degrees and feel the difference in force, then return it to it's original position and do the same with the right one.

When you rotate the temporary magnet, you should feel equal force attracting it to the pole, because the induced pole will always be towards the permanent pole. When you rotate the permanent magnet, the other bar is being placed further away from both of the poles and hence should result in a lesser force attracting it, and you should feel less force pulling them together.

Someone tell me if I'm wrong.
