The source of magnetism is
A)polarization
B)magnetic monopoles
C)electrons
D)protons
Both permanent magnetism and electromagnetism results from the motion of electrons. Positive ions such as protons can produce magnetic fields also, but they are not a major source of magnetism.
The correct answer is C) electrons. The source of magnetism is the movement of electrons. When electrons move in a particular direction, they create a magnetic field. This magnetic field is responsible for the attractive or repulsive forces observed in magnetized objects.
The correct answer is C) electrons.
To understand why electrons are the source of magnetism, let's break it down. Magnetism is the result of the motion of charged particles, such as electrons. When electrons move, they create a magnetic field. This magnetic field is the fundamental source of magnetism.
One way to observe this is by looking at the arrangement of electrons in atoms. In magnetic materials like iron, nickel, and cobalt, the electrons are not evenly distributed. Instead, there are unpaired electrons that can freely move and create a magnetic field. These materials are thus able to be magnetized and exhibit magnetic properties.
It's important to note that magnetic monopoles, represented by option B, do not actually exist as freely moving particles in nature. Unlike electric charges, which can exist in both positive and negative forms, magnetic poles always come in pairs - a north pole and a south pole. This is known as the magnetic dipole.
So, in conclusion, the source of magnetism is the motion of electrons, as they create a magnetic field when they move.
