We have a bunch of different magnets in the house but on the whole none that were super powerful. They weren’t strong enough to do the experiments that we wanted to do.
So, we bought some really strong magnets. Now these magnets are definitely not the type to leave around the house for little people to play with at will!! There would be disastorous concequences of non-functioning phones and kurput electrical equipment. So, beware if you decide to do this at home! The packaging was full of strong warnings!
We used these super strong magnets to make…..another magnet!
Little Man stroked a large needle a few times with one side of the magnet and hey presto….the needle became magnetic. The amazing thing was that the magnet stayed magnetic for ages! I though maybe it would be magnetic for a few minutes and we’d have to go through the process again. However, the needle picked up the paper clips and even they became magnetic, I found them sticking to some electrical devise the next day!!
We also used the magnetic needle to create a compass. We laid the needle on some cardboard which we placed in a bowl of water and hey presto. We spun the card around and it would always settle with the needle pointing north! How very cool.
Have you done any magnetic experiments? Did you get the results you imagined?
