Question

Basic source of magnetism
A) Charged particles alone
B) Movement of charged particles
C) Magnetic dipoles
D) Magnetic domains

Answer 1

Hint: One aspect of the combined electromagnetic force is magnetism. It refers to physical phenomena that occur as a result of the force exerted by magnets, which are objects that generate fields that attract or repel other objects.

Complete answer:
A magnet is an object or material that generates a magnetic field. This magnetic field is invisible, but it is responsible for a magnet's most notable property: a force that attracts or repels other ferromagnetic materials such as iron, steel, nickel, cobalt, and others.
Magnetism is a force that attracts (pulls objects closer) or repels (pushes objects away) objects that contain a magnetic material such as iron (magnetic objects). In layman's terms, it's a property of substances that attract or repel other objects.
Magnetism is caused by the motion of electrically charged particles. The magnitude of the charge, the velocity of the particle, and the strength of the magnetic field all affect the force acting on an electrically charged particle in a magnetic field.
Magnetism is caused by the movement of charged particles. Magnetism affects all materials, though some are more magnetic than others. The strongest effects, known as ferromagnetism, are seen in permanent magnets made of materials such as iron. This is the only form of magnetism strong enough to be felt by people, with rare exceptions.
Thus, option (B) is correct.

Note:
A permanent magnet is created when the alignment of unpaired electrons persists in the absence of an external magnetic field or electric current. Ferromagnetism is the cause of permanent magnets. Because permanent magnetism was first observed in a form of natural iron ore called magnetite, the prefix "Ferro" refers to iron.
