Magnetism which is present only when the material is under the influence of an external field is called _______________.
AI Explanation
The correct answer is B) induced magnetism.
Induced magnetism refers to the magnetism that is present in a material only when it is under the influence of an external magnetic field. This means that the material does not have any inherent magnetic properties on its own, but it becomes magnetized when exposed to an external magnetic source.
The other options are incorrect:
A) Residual magnetism refers to the magnetism that remains in a material even after the external magnetic field is removed.
C) Permanent magnetism refers to the magnetism that is inherent in certain materials, such as iron or nickel, and does not require an external magnetic field to be present.
D) Terrestrial magnetism refers to the Earth's own magnetic field, which is a natural phenomenon and not related to the concept of induced magnetism.
