Q.2 what is ferromagnetic materials?
Ans. Ferromagnetism is the fundamental method by which certain substances form permanent magnets or are attracted to other magnets.
ㅤㅤㅤㅤㅤOR
Paramagnetic materials have a small, positive susceptibility to magnetic fields. Ferromagnetic materials have a large, positive susceptibility to an external magnetic field. They exhibit a strong attraction to magnetic fields and are able to retain their magnetic properties after the external field has been removed.
Yes / No questions are also called closed questions because there are only two possible responses: Yes or No. When forming a Yes / No question, it must include one of these verbs: BE, DO, HAVE, or a modal verb. It is impossible to ask a Yes / No question without one of these verbs.
