Question

according to the text, what makes lodestone a permanent magnet? lodestone is formed during volcanic eruptions lodestone is long - lasting and difficult to remove lodestone continuously produces it own magnetic field lodestone only produces a magnetic field when it is near steel

Explanation:

Permanent magnets generate their own persistent magnetic fields. Lodestone, a natural permanent magnet, has this inherent property. The other options are incorrect: volcanic formation is its origin not the reason for being a permanent magnet; "long-lasting and difficult to remove" describes magnetism persistence not the cause; and the last option describes temporary induced magnetism, not permanent magnetism.

Answer:

Lodestone continuously produces it own magnetic field
