Roughly speaking, there are only two options here: either a component reacts to the magnet, or it doesn't. This means that you can easily have a mixture of two substances that either both react to the magnet, or none of them reacts to it, so that you can't use the magnet to separate them.
No!The smallest particle in which a magnet still has the same magnetic properties is a called a domain. If you split this domain into other remnants, then that particle shall seize to become a magnet and shall just be a piece of matter
No, but it is only a matter of time before somebody produces one.
No magnetism is not matter it is a force of energy caused by perpendicularly(sorry for the big word)aligned poles in specific metals. Magnetism is also caused by rapidly churning metals. Short answer: No
A magnet. It is described as a Magnet.
No, calcite is not magnetic and does not react to a magnet because it is composed of non-magnetic calcium carbonate.
Technetium is paramagnetic.
React to the nearby presence of another magnet
Physics is the study of how energy and matter react.
A magnet is a solid state of matter. It is typically made of materials such as iron, cobalt, or nickel that have magnetic properties.
Yes, if the substance has magnetic properties.
they repel each other
no, magnet needs to be close to winding, not touching it
Cold causes matter to contract. Heat causes matter to expand.
chemical property
It doesn't matter on the orientation, it is the attraction of the magnet to pull the contact and complete the circuit that matters.
because the iron filings are in a magnetic field
