Question

Read the passage carefully.
The earth’s magnetic field extends millions of kilometers into outer space and looks very much like a bar magnet. The earth’s south magnetic pole is actually near the North Pole and the magnetic north pole is in Antarctica! This is why a magnetic compass’s North Pole actually points north. The Earth’s magnetic field extends far and wide but is very weak in terms of field strength.
Earth’s Magnetism is generated by convection currents of molten iron and nickel in the earth’s core. These currents carry streams of charged particles and generate magnetic fields. This magnetic field deflects ionizing charged particles coming from the sun (called solar wind) and prevents them from entering our atmosphere. Without this magnetic shield, the solar wind could have slowly destroyed our atmosphere preventing life on earth to exist. Mars does not have a strong atmosphere that can sustain life because it does not have a magnetic field protecting it.
The earth’s magnetic poles are not aligned to the actual geographic north and south poles. Instead, the magnetic south pole is in Canada while the magnetic north pole lies in Antarctica. The magnetic poles are inclined by about 10 degrees to the earth’s rotational axis. So, all this time your compass was really pointing to Canada, not the true North!
In regions near the magnetic poles, compasses are virtually useless.

Answer the following questions:
Q.1 The earth’s magnetic field is very vast, but we cannot feel it. Why?
Q.2 What is the cause of earth’s magnetism?
Q.3 What will happen if our magnetic field becomes weaker or disappears?
Q.4 Mars has a strong atmosphere because it has a magnetic field protecting it. True or False?
Q.5 Where is the magnetic North pole and magnetic South pole situated?
