Question

magnetic flux of earth is large, small ,zero​

Answer 1

Answer:

large is the correct answer

Answer 2

• The Earth’s magnetic field is just 0.000025 to 0.000065 Tesla.

• But it’s enough to deflect dangerous radiation from the Sun - which is what makes life on Earth possible.

• Contrary to popular belief, Earth’s magnetic field is extremely weak, many times more vulnerable than even a typical ferro-ceramic bar magnet.

• Earth’s surface strength is roughly 25-65 microteslas, or 0.25-0.65 gauss, whereas a tiny bar magnet is around 10,000 microteslas or 100 gauss. That’s ~40,000 times stronger!

• Yet, how does the Earth’s weak magnetic field make compasses point north from anywhere?

• That’s because while the Earth’s magnetic field at one point is minute, the size of the Earth’s field magnet is small, so the total force has towered over the entire force of a small bar magnet.

• A magnetic field is measured in tesla.

• A 1 Tesla neodymium magnet is a powerful magnet.
