Hello 3A,
I really can't seem to upload the 2 other videos that I have shown to the class (observation made during the discovery lesson on 16 July lesson). But I trust that all of you were paying close attention to how the magnet flip/spins when we rotate the other magnet on a different side.
Monster lodestone
A bar magnet & U-shaped magnet
Notice how the iron filings rearrange along the lines of the magnetic field (recall that magnetic field is invisible, so we use iron filings to "see" the magnetic field lines). Here's another video:
What can you conclude about the magnet's magnetic attraction?
Do you now know why the magnet's magnetic attraction is the weakest between its 2 poles?
So looking back at the discovery lesson and the Monster Lodestone video, can you explain about magnetic forces? Why does the magnet spins/flips/moves left & right when another magnet is brought close to it?
Remember to complete your mindmap on Magnets. If you want to try out drawing the magnetic field drawings based on the video, that would be even better.
Have a restful weekend! To the Malay students, Selemat Hari Raya Puasa! (:
Why does the paper clips attracted to the lodestone is standing up?
ReplyDeletedoes the iron filings works on temporary magnets,like a magnetised iron nail?
