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.

∙ 13y agoIf 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.

What would happen if the earth didn't have a magnetic field?
If we didn't have the earth's magnetic field, eventually all of the harmful and deadly rays from the sun would destroy life on earth.
Are most substances magnetic?
Technically all substances are magnetic in some way: it's either ferromagnetic (what most people would consider "magnetic"), paramagnetic (weakly attracted to a magnetic field), or diamagnetic (weakly repelled by a magnetic field). Not many substances are "magnetic" in the usual lay meaning of the word, though.
What is an example of magnetic field?
The atmosphere of the earth is a magnetic filed
Best description of a magnetic field line?
A magnetic field line shows the direction a compass needle would point
What happens to a current carrying wire in a magnetic field when it is reversed?
the wire would be deflected perpendicular to the magnetic field in the opposite direction.
What would happen if the direction of the current through a hall probe is reversed?
The idea is that the magnetic field of the device reacts with the external magnetic field. If the current is reversed, the magnetic field would also be reversed, and the reading would be the opposite.
What will happen if the whole world is in he influence of magnetic field?
you would get bummed by an alien
What would happen if the earth didn't have a magnetic field?
If we didn't have the earth's magnetic field, eventually all of the harmful and deadly rays from the sun would destroy life on earth.
What happen to the magnetic field of a wire when change the direction of the current in the wire?
Direction of the magnetic lines too would get changed
What would happen if field lines crossed?
Then, at some point, the field would go into two directions simultaneously, which doesn't make much sense. The magnetic field lines form continuous closed loops.The tangent to the field line at a point represent the direction of the net magnetic field B,at that point.The magnetic field lines do not intersect,if they did, the direction of the magnetic field would not be unique at the point of intersection.
Region around a magnet in which magnetic force can act?
Magnetic freild
What would happen if a pigeon detected a magnetic field?
There are theories around that some birds can actually detect magnetic fields, which they use to navigate on long migrations.
What would happen if Earth's magnetism get reversed?
There would be a temporary weakening of the magnetic field during the reversal. After the reversal the only noticeable difference would be that compasses now point south instead of north. Navigation systems that use the magnetic field would need to be recalibrated.
How is the force affected when the current is reversed in a magnetic field?
The magnetic field would reverse.
What happens to the magnetic field if the current in the wire increases?
If the current in the wire increases, the magnetic field also increases.
What is induced by the rapid alternation of a magnetic field?
you would induce voltage therefore chanfing the magnetic field
