Q. What creates a magnetic field at the atomic level?
Magnetic fields are produced by moving electric charges. Everything is made up of atoms, and each atom has a nucleus made of neutrons and protons with electrons that orbit around the nucleus. Since the orbiting electrons ≠are tiny moving charges, a small magnetic field is created around each atom.
Q. What particle is responsible for magnetism?
If the majority of electrons in the atom spins in the same direction, a strong magnetic field is produced. The direction of the electrons spin determines the direction of magnetic field. If the same number of electrons in the atom spins in opposite directions, the electron spins will cancels out.

Q. Where does magnetism come from?
Magnetism arises from two types of motions of electrons in atoms-one is the motion of the electrons in an orbit around the nucleus, similar to the motion of the planets in our solar system around the sun, and the other is the spin of the electrons around its axis, analogous to the rotation of the Earth about its own …
Q. How does something become magnetized?
Ferromagnetism is a phenomenon that occurs in some metals, most notably iron, cobalt and nickel, that causes the metal to become magnetic. The atoms in these metals have an unpaired electron, and when the metal is exposed to a sufficiently strong magnetic field, these electrons’ spins line up parallel to each other.
Q. Can liquids be magnetized?
However, it is possible to “magnetize” ordinary liquids by dispersing into them very fine magnetic particles. The resulting liquid becomes a homogeneous magnetic material, just like a solid, but it retains its fluid characteristics.
Q. Is the Earth’s core magnetic?
The core of the Earth is also an electromagnet. Although the crust is solid, the core of the Earth is surrounded by a mixture of molten iron and nickle. The magnetic field of Earth is caused by currents of electricity that flow in the molten core.
Q. What is the most magnetic thing in the world?

Q. Who is the king of the magnetic materials?
Iron is the king of magnetic materials—the metal we all think of when we think of magnets.
Q. Is the most magnetic material in nature?
The most magnetic material in nature is the mineral magnetite, also called lodestone (see Figure below). The magnetic domains of magnetite naturally align with Earth’s axis.
Q. Which material is more magnetic than iron?
The iron and nitrogen compound proved 18 percent more magnetic than iron cobalt in tests done by Jianping Wang, a physicist at the University of Minnesota. There also appears to be a “new physics” at work in the substance, but physicists at other labs must replicate the experiment and verify the work.
Q. Is iron the most magnetic?
Most people think of iron as a magnetic material. Iron is ferromagnetic (attracted to magnets), but only within a certain temperature range and other specific conditions. So, most magnetic materials are metals. Other magnetic elements include nickel and cobalt.
Q. Is iron a ferromagnetic material?
Only certain materials, such as iron, cobalt, nickel, and gadolinium, exhibit strong magnetic effects. These materials are called ferromagnetic. Ferromagnetic materials will respond strongly to magnets and can also be magnetized themselves.
