Can plastic allow me to see magnetic fields and where can I find it?

AI Thread Summary
Iron filings can effectively demonstrate magnetic fields to children by aligning with the field when placed on a glass plate or paper over a magnet. This visual representation helps in explaining how magnets work. Additionally, there are specialized products available for purchase that can aid in this demonstration. The discussion also mentions a specific type of plastic that allows viewing magnetic fields, but further details on its availability were not provided. Exploring educational science suppliers may yield options for both iron filings and the plastic mentioned.

hello I was hoping someone could tell me a way to show my children a way to see a magnetic field?they are playing with magnets and don't underststand the way i explained how they work . if i could show them they might start to understand ... thanks in advance for your reply

You can use iron filings and show how they align to the magnetic field. This can help them visualize the field and make it easier to explain how it works when you explain it.
 
It would be best to put the filings on a glass plate or sheet of paper with the magnet underneath. This way you can easily remove the magnet and put the filings back in a container.

Or you can purchase this http://www.sciencefirst.com/vw_prdct_mdl.asp?prdct_mdl_cd=20110" .

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
