Is a piece of metal being magnetic a chemical change?
Other examples of physical changes include magnetizing and demagnetizing metals (as is done with common antitheft security tags) and grinding solids into powders (which can sometimes yield noticeable changes in color).
Can chemicals be magnetic?
Magnetochemistry is concerned with the magnetic properties of chemical compounds. Magnetic properties arise from the spin and orbital angular momentum of the electrons contained in a compound. Molecular compounds that contain one or more unpaired electrons are paramagnetic. …
What is magnet chemically?
All magnets are made of a group of metals called the ferromagnetic metals. These are metals such as nickel and iron. Each of these metals have the special property of being able to be magnetized uniformly. The most common way that magnets are produced is by heating them to their Curie temperature or beyond.
Why is magnetism considered to be a chemical property?
You don’t get very far in chemistry without looking at energy relationships, nor in physics without looking at the properties of specific materials. Magnetism is the charge density increase experienced when a charge moves relative to another (due to length contraction in relativity see Lorentz contraction ).
Why do elements have a magnetic effect on each other?
Answer Wiki. Magnetic effects of elements happen because electrons have a property called spin and due to the laws of induction a spinning charged particle will have a magnetic field.
How is the charge density of a charge affected by magnetism?
Magnetism is the charge density increase experienced when a charge moves relative to another (due to length contraction in relativity see Lorentz contraction ). The charge density increase in the direction of motion is felt as a new force perpendicular to the motion.
