State one importance, each of magnetic elements of earth's magnetism, in real life.
Answers
Answer:
our body also acts like electromagnet as electric signals flow in our body
Answer:
There are three components that are responsible for the magnitude as well as the direction of the earth's magnetic field:
i)Magnetic declination.
ii)Magnetic inclination or the angle of dip.
iii)Horizontal component of the earth's magnetic field.
Explanation:
i)Magnetic declination is an important concept for accurate navigation. A compass will always point along the lines of magnetic force (which converge on what are called the magnetic poles). The angle between the direction of force and the direction of the geographic north pole is called the declination.
ii) Magnetic inclination is especially important in aviation, as it causes the airplane's compass to give erroneous readings during banked turns and airspeed changes.Compass needles are often weighted during manufacture to compensate for magnetic dip, so that they will balance roughly horizontally.
iii)The Horizontal component of the Earth's magnetic field serves to deflect most of the solar wind, whose charged particles would otherwise strip away the ozone layer that protects the Earth from harmful ultraviolet radiation.
