Question

Which is an example of reverse pWhich is an example of reverse polarity?

a)Earth’s magnetic field lines up in the same direction as the present magnetic field

b)the north magnetic pole is aligned with the present north magnetic pole

c)Earth’s magnetic field lines up in a direction opposite of the present magnetic field

d)the south magnetic pole lines up with the present south magnetic pole

Answer 1

b) is the right option

Answer 2

Option c)Earth’s magnetic field lines up in a direction opposite of the present magnetic field

Earth’s magnetic field lines up in a direction opposite of the present magnetic field an example of reverse pWhich is an example of reverse polarity.

• Imagine, for instance, that your toaster was connected to an outlet that had reverse wiring. You might get shocked if you put your knife near the metal of the toaster while trying to get your toast out. Reverse polarity can be extremely hazardous because of this.
• A change in the polarity of the earth's magnetic field is referred to as a magnetic polarity reversal. Throughout geologic time, this has happened at random periods.
• The magnetic field of the Earth has repeatedly reversed itself over time, according to scientists. The field and the rocks that record it have "normal" polarity when the field faces the north magnetic pole, as it does right now.
• The primary direction of the Earth's field has cycled between times of normal polarity, when it was the same as it is now, and reverse polarity, when it was the opposite. These intervals are known as chrons.
