Magnetic resonance imaging (MRI) is a medical imaging technique that located in
hospitals and radiology centers. MRI uses a strong magnetic field and radio waves
to create detailed images of the organs and tissues within the body.
(i)
MRI system operators must make sure not to carry any metallic objects
when they enter the room that house the MRI, even when the machine is not
operating. Give the reason.
(ii)
What happens if a magnet was hitted with a hammer repeatedly? Explain
your answer.
Robots are used in automobile industries to weld two components at specific
locations. Thus, the end position of the robot arms must be determined accurately
in order to weld the components at the precise position. In selecting a proper
material for the robot arms design, identify the factors must be considered for this
application.
