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...
