Using a different grammatical structure and expressions:
It is not possible to use a graphite crucible for melting magnetic materials. Graphite, being a non-magnetic substance, lacks the capacity to create or maintain a magnetic field. Consequently, it is unsuitable for melting magnetic materials as it cannot effectively engage with or confine them.
No, a graphite crucible cannot be used for melting magnetic materials. Graphite is a non-magnetic material and does not have the ability to generate or sustain a magnetic field. Therefore, it would not be suitable for melting magnetic materials, as it would not be able to interact with or contain them effectively.
No, a graphite crucible cannot be used for melting magnetic materials as graphite is not magnetic and will not interact with magnetic substances.
