Question

A compass contains a magnet. The magnet responds to Earth’s magnetic field. The magnet’s north pole points north from most locations on Earth. Based on what you learned about magnetic force, make three predictions. Predict the approximate size of Earth’s magnetic field and the approximate location of its North and South Poles. Give a reason for each prediction.

Answer 1

Step-by-step explanation:

A field is a region of space where force is felt or exerted.

A magnetic field as such is an area where the impact of magnetic force can be felt.

The earth behaves like a giant bar magnet due to movement of liquid metals in the outer core. This giant magnet exerts a magnetic field on the entire earth. The core of the earth falls at the centre of the globe and it dissipiates magnetic force outwards.

In terms of the magnetic field of the earth, it covers the entire planet due to the location of its source.

The poles are deflected just a little bit from the geographic north and south by a little angle. This angle is known as magnetic declination. It varies from time to time due to the strength of the magnetic field.
