1. What is magnetisation? How can you magnetise a magnetic material using a magnetic material and a magnet?
Explain.
Answers
Answer:
a process that takes place in a ferromagnet that is exposed to an external magnetic field; this process leads to an increase in the intensity of magnetization of the ferromagnet in the direction of the field.
We can magnetize a material by rubbing it against a strong magnet. When a magnetic material is brought near the magnetic field of a magnet, its atoms start aligning itself to the field. So, when we rub the material over the magnet the material will be magnetized for a certain period of time.

Answer:
In classical electromagnetism, magnetization or magnetic polarization is the vector field that expresses the density of permanent or induced magnetic dipole moments in a magnetic material. ... Physicists and engineers usually define magnetization as the quantity of magnetic moment per unit volume
