Question

Problem 4. You are designing magnetic motors. A colleague1 insists that like magnetic poles attract— north poles attract north poles and south poles attract south poles. You feel the need to remove this idea from his head. You possess three unlabeled bar magnets (that is, you don’t know which ends are N or S). Surely that will be enough. . .

Answer 1

We can do a simple experiment. Just place two magnets under a plastic sheet. Put the any two poles facing each other a few inches apart. Then sprinkle iron filings on the plastic sheet. The magnetic force fields will cause the iron filings to show a blank area between the two magnets and the force fields curving away from the area between the two magnets. If there is a gap in iron fillings between. The magnets then it's like poles , if there are lines from end of one magnet to end of second magnet, then it's opposite poles
