Magnetic powder, iron powder, etc.
Iron Filings.
What else can I help you with?
What materials could you use to see the field lines around a magnet?
Magnetic powder, iron powder, etc.Iron Filings.
What can happen if you keep a magnet to your head?
That would depend on the strength of the magnetic field of the magnet. As magnetic fields can influence electrical current, and our brains work on a massive series of electrical impulses, it's possible that there could be some interaction, but the magnetic field would need to be immense before any noticeable side effects became aparrent. Magnetic fields are all around us, the earth is basically one big magnet (that's why a needle in a compass points to north) so you could say life on earth is used to exposure to magnetic fields.
Could glucose get separated from a magnet?
Glucose is not a metal and can not be separated using a magnet.
Which of the following could a magnet float over network solid semiconductor superconductor molecular solid?
A superconductor.
How does a permanent magnet stay magnetic?
Inertia. A system will not change it's properties until an external force is applied. Permanent magnets DO decrease in strength by being used as they are subjected to external magnetic fields that oppose them. How much a permanent magnet will be affected by the external field depends on it's Hysteresis loop characteristics.
Is a pencil magnetic or nonmagnetic?
Yes a pencil could be magnetized. But it could only be magnetized with pencils only not a magnet.
Can a magnet be broken?
Not exactly. All pieces of the magnet retain their ferrous properties, but if they were (for example) dropped, then the shock of the fall could potentially make them lose a bit of magnetism. Extreme temperature changes and high power electric discharges could also decrease the power of the magnet.
What are some fun things can you do with a magnet?
1. Build a motor/generator; 2. (This answer would be sick, so I left it out) 3. Create magnetic fields (duh) 4. Ever heard of a game called Polaris? Well, just mess with magnets, and you could end up making them jump over each other. 5. You could hold a magnet under a table, and place another on top of the table. See what happens when you move the one underneath around. 6. You could put iron fillings in a jar, close the lid, then move the magnet around outside it. (actually, just messing with iron fillings in general is fun) 7. You could grind up cheerios (any cereal works well enough) and move a magnet around in the result. You should have particles stuck to the magnet. This is the iron in the cereal! 8. I hear if you get a strong enough magnet, you can destroy many electronic appliances, including a TV and a computer.
How will a crocodile be affected if it wandered near a strong magnet?
If a crocodile wandered near a strong magnet, it would likely not be affected in any significant way. Crocodiles do not have magnetic materials in their bodies that would react strongly to magnetic fields, as their physiology is primarily composed of organic tissues and fluids. However, if the magnet were strong enough to affect nearby metal objects, it could cause distractions or disturbances in the crocodile's environment, but the crocodile itself would remain unaffected.
How could you separate iron filings from sand?
You can take a magnet and put it around it and it will work
Could a magnet float over a network solid?
You think probable to magnetic levitation due to interaction of magnetic fields.
What happens if you put a magnet in a drawer full of nails and the magnet doesn't pick any of the nails?
If the magnet does not pick up any of the nails in the drawer, it could be due to a weak magnetic field of the magnet or the nails being made of a material that is not attracted to the magnet, such as stainless steel. Some nails are made from non-magnetic materials, so they wouldn't be attracted to a magnet.
