We would we be exposed to radiation bursts from the Sun--the kind which erupt of the order of once a year (or less).We are shielded by the atmosphere, an absorber comparable to 10 feet of concrete. Solar bursts cannot penetrate that thickness. It is true that the magnetic field of Earth deflects the fast protons of those bursts even before they reach the top of the atmosphere--but that magnetic shield fails near the magnetic poles, yet no extra radiation is detected there at ground level.Without magnetic protection, the solar wind emitted by the Sun would also reach the atmosphere. Could it perhaps strip our atmosphere away?Maybe, given a few billion years, but not quickly. Venus lacks a magnetic field and experiences a stronger solar wind, being closer to the Sun, yet retains a very dense atmosphere. Mars, without a global-size magnetic field, has only a thin one--but the gravity holding down its atmosphere is only 1/3 of ours.
What else can I help you with?
What would happen to the strength of the field if the current was increased?
If the current in a wire is increased, the strength of the magnetic field around the wire would also increase. This is because magnetic field strength is directly proportional to the amount of current flowing through the wire.
What must happen in order electric charges to produce a magnetic field?
Electric charges must be in motion to produce a magnetic field. When electric charges move, they generate a magnetic field around them. The strength of the magnetic field depends on the speed and direction of the moving charges.
How often does the earths magnetic field change polarity?
The Earth's magnetic field has changed polarity hundreds of times in the geological past. This phenomenon is known as geomagnetic reversal. The frequency at which these reversals occur is not regular, but on average, it is estimated to happen every few hundred thousand years.
Will the polarity of the earths magnetic field change in 2012?
There is no scientific evidence to suggest that the polarity of Earth's magnetic field will change in 2012 or any time soon. The Earth's magnetic field has undergone numerous reversals throughout its history, but these events occur over thousands of years, not within a single year.
When you placed the magnet next to the iron?
nothing will happen dumbazz because it isnt magnetic
What will happen if the flow of hot rock in earths mantle if the planets core eventually cools?
The flow of hot rock in earths mantle will stop and Earth's magnetic field will disappear
What would happen to the strength of the field if the current was increased?
If the current in a wire is increased, the strength of the magnetic field around the wire would also increase. This is because magnetic field strength is directly proportional to the amount of current flowing through the wire.
What will happen when the number of turns of wire and the current flowing them increases?
The strength of the magnetic field inside the coil increases.
What must happen in order electric charges to produce a magnetic field?
Electric charges must be in motion to produce a magnetic field. When electric charges move, they generate a magnetic field around them. The strength of the magnetic field depends on the speed and direction of the moving charges.
Will the earths magnetic poles ever switch causing a polar shift?
This has happened several times in the past at irregular intervals, so it seems likely it will happen again in the future.
What kind of destruction would happen if the earths core stopped rotating?
it wil cancel the magnetic field whch will cause radiation from the sun to penitrate and kill off life on earth
When did Magnetic Soccer happen?
Magnetic Soccer happened in 1992.
What will happen if war continues?
if the world continues everyone would die
Why are northern lights made?
the northern lights are caused by magnetic energy being shot out of the passing through the earths atmosphere it also happen in the southern hemisphere because the atmosphere is weaker in these parts

When did Crisis on Infinite Earths happen?
Crisis on Infinite Earths happened in 1919-04.
When did Super Magnetic Neo happen?
Super Magnetic Neo happened in 2000.
