You are given a material which produces no initial magnetic field when in free space. When it is placed in a region of uniform magnetic field, the material produces an additional internal magnetic field parallel to the original field. However, this induced magnetic field disappears when the external field is removed.
What type of magnetism does this material exhibit?

diamagnetism
paramagnetism

ferromagnetism

Once again, you are given an unknown material that initially generates no magnetic field. When this material is placed in a magnetic field, it produces a strong internal magnetic field, parallel to the external magnetic field. This field is found to remain even after the external magnetic field is removed.
Your material is which of the following?
diamagnetic
paramagnetic
ferromagnetic

What type of magnetism is characteristic of most materials?
