It is called echolocation. They hear sounds which "bounce" off inanimate objects (cave walls etc......) and they are naot blind.
Yes. Magnetic lines of force penetrate paper with little to no difficulty.
Emeralds are not magnetic because they do not contain any magnetic properties. The magnetic properties of a material depend on its atomic structure and the presence of unpaired electrons, which are not present in emeralds.
Yes, metal can be deflected by magnetism through the use of a magnetic field. When a metal object interacts with a strong magnetic field, it can be pushed or pulled in a certain direction due to the magnetic forces at play.
Yes, paleomagnetism is the study of the magnetic properties of rocks and sediment to determine the past behavior of Earth's magnetic field. It provides insight into the movement of tectonic plates, paleoclimate conditions, and the history of the Earth's magnetic field.
In depends upon how hot you are talking about. Cold would be my best answer in general. If you are comparing the magnetism between say 10 below zero and 100 F then there would be no discernable difference. If you should heat the metal to red-hot, the magnetism would be lost after the metal has cooled.
Yes, the "old" televisions use magnetism to controll the movements of the electrons.
Yes, it does.
yes
Yes, magnetism passes through polystyrene
yes ,actual navigation use electronic navigation and paper one soo they need compas and sundails
Yes, some research suggests that bats may use the Earth's magnetic fields for navigation during their nightly flights. However, the exact mechanisms and extent of this ability are still being studied and are not fully understood.
yes
yes, yes it does
Yes
yes
Yes, This is the navigation. The G.P.S is a navigation device. Where is the navigation?
Yes
