Is a magnet earaseing a computer disk a chemical or physical change?
The answer is physical:)
Is separating sulfur and iron with a magnet chemical or physical change?
This is not a change at all. However it is physical when you use a magnet to physically seperate (by manetic force) .
Is a tree growing a chemical or a physical change?
First of all lets understand Physical & Chemical Change. Physical change can be reversed and the chemical properties of the two states remain the same. Chemical change cannot be reversed and the chemical properties of the two state are entirely different. Now lets get back to the question. Is growing a tree a physical or a chemical change. The growing of a tree requires chemical changes, primarily the conversion of water and carbon dioxide into cellulose and oxygen. So the growth results primarily from chemical changes.
When two substances are mixed together a magnet can remove particles from a substance.?
A magnet can remove particles from a mixture but not from a chemical compound.
How do you separate salt and iron shaving?
I can think of two ways: 1. Pour in some water. The salt will dissolve and the iron won't, then filter out the water. 2. Grab a magnet. The iron will stick to the magnet, the salt won't. Chemistry is fun!
Is heating a bar magnet chemical or physical change?
Heating a bar magnet is a physical change because the magnet does not undergo a chemical reaction. The heat energy causes the atoms in the magnet to vibrate, which disrupts the alignment of the magnetic domains within the magnet, thereby reducing its magnetic strength.
Do shaving blades are attracted by magnet?
no it dont attrack

How do you remove the magnet out of the WWE spinner belt?
shaving cream
Is using a magnet to pick up a steel nail an example of turning chemical energy to produce kinetic energy?
No, using a magnet to pick up a steel nail is not an example of turning chemical energy into kinetic energy. In this case, magnetic energy is used to attract the nail, causing it to move towards the magnet. Chemical energy would involve the breaking or making of chemical bonds to produce kinetic energy.
Is picking up iron filings with a magnet a chemical reaction?
No, a chemical reaction is when the atoms are not mixed together but chemical bonded together. You know when a chemical reaction has happened when you can smell, hear or see things reacting.
Is making iron into a magnet a physical change?
To make an iron bar into a magnet you need to get a bar magnet and stroke the iron one way when you get to the end of iron take the magnet off and jump it back to the start and stroke repeat this several times and your bar will soon become magnetic. This is only temporary, therefore the iron will become normal after the magnetic field rubs off. This means that making iron into a magnet is indeed a physical change.

What is A magnet erasing a computer disk is that a physical or chemical?
Magnetic erasing of a computer disk is a physical change. The polarity of the molecules in the storage media is altered, but the material retains the same composition so it is NOT a chemical change.
Does temperature affect the strength of a magnet is it chemical science?
NO!!! the strength of magnet is not affected by temperature
What type of magnet is lodestone?
Lodestone is an example of a natural magnet.
