When placed inside of a magnetic field, the magnetic field that electrons generate aligns in the opposite direction of the applied magnetic field.
Also, someone who is very popular and attracts people has a charming personality. A powerful speaker that attracts many fans has an engaging way of speaking. A magnetic person is attracted to you as if by a magical magnetism. Both meanings of magnetic have to do with the force of attraction. Only ferromagnetic materials such as iron, cobalt and nickel are attracted to magnetic fields strong enough to be considered truly magnetic.
All magnetic fields contain energy, also called magnetic energy. In physics, it is a constant. Magnetic energy is a form of energy from moving charge carriers (electrons) because magnetic fields are generated by electric currents.

Answer: Option (c) is the correct answer.
Explanation:
As we know that density the amount of mass present in per unit volume.
Mathematically, Density = ![\frac{mass}{volume}](https://tex.z-dn.net/?f=%5Cfrac%7Bmass%7D%7Bvolume%7D)
So, it means that density is inversely proportional to volume. Hence, when there will be decrease in density of a substance then there will be increase in its volume. That is, expansion of substance will take place.
Also, boiling point of copper is 2,562 degree celsius but we are heating it up to a temperature of 95 degree celsius. This means that copper will remain in liquid state at this temperature.
Thus, we can conclude that a change which occurs in a sample of copper is that copper sample will expand.
Answer:
100 times more acidic.
Explanation:
If you look at the pH scale, pH2 is 2 "jumps" away from pH4, therefore, pH2 is 100x more acidic than pH4.
