What would happen to people if the magnetic field was gone?

Answer 1

If the magnetic field disappeared, we'll be in danger of gamma rays like solar winds and cosmic rays because magnetic fields shields those things.

Without the magnetic field, compasses will no longer work and we would need to find other ways to measure direction to navigate. Also, birds depend on the magnetic field for navigation during migration and would no longer be able to do that.

Answer 2

If the Earth's magnetic field shut down, or even diminished slowly as it reversed polarity, then we would probably be in some trouble. The magnetic field shields us from many of the charged particles from the Sun, and these are known to be damaging.

This would not be an immediate extinction of life - rather the rates of mutation and of cancers would increase. But the Cockroaches wouldn't mind, for they are very resistant to radiation. But that gives the clue that radiation intolerant species would diminish or change, and tolerant organisms would flourish.

The Earth's magnetic field is produced by electrical currents flowing round the Earth, roughly parallel to the Equator. But variations in that path would cause disturbances in the seen effect, which primarily is the magnetic field.

Answer 3

Without Earth's magnetic field, people would be exposed to harmful cosmic radiation from the sun and outer space, increasing their risk of developing cancer and other health problems. Navigation systems that rely on the magnetic field, such as compasses, would no longer work correctly, leading to potential disruptions in transportation and communication systems. Additionally, the absence of the magnetic field could affect migrating animals and disrupt ecosystems.

Answer 4

all the stuff on our fridge would fall off
