Because the gravity of earth was closer together.
No, the moon does not have a global magnetic field like Earth. Some localized magnetic fields have been detected on the moon's surface, but they are much weaker than Earth's magnetic field.
Sun spots (magnetic storms).
Mercury fits this description, as it has craters, cliffs (known as scarps), and a weak magnetic field. Mercury's magnetic field is only about 1% as strong as Earth's magnetic field.
Saturn has a weak magnetic field compared to other planets like Earth or Jupiter. Its magnetic field is primarily generated by the motion of its metallic hydrogen interior. The magnetic field is not well-aligned with the planet's rotation axis, causing irregularities in its magnetic environment.
Jupiter's magnetic field is caused by the flow of electrically conducting material in its metallic hydrogen layer. As Jupiter rotates, this material generates a magnetic field. The combination of the planet's rotation and its metallic hydrogen layer results in its strong magnetic field.
it's not
To start if we didnt have a magnetic field we would be fried by the suns radiation. The northern lights are evidence that we have a magnetic field surrounding earth.
Mercury's magnetic field was created in 1974-04.
the magnet field is the strongest well the summer solstic when the suns gravitational pull is the strongest
A magnetic field is created when electric charges move. This movement generates a force that aligns the charges in a specific direction, creating a magnetic field around the moving charges.
The magnetic field in an alternator is created by the rotor, which is an electromagnet that produces a rotating magnetic field as it spins. This magnetic field induces an alternating current in the stator windings through electromagnetic induction, which is then converted to usable electrical power.
The earth has a solid iron core, which creates an electric magnetic field around us. Only a few of the sun's rays can get through that magnetic field.
The magnetic field for an electromagnet is created by the flow of electric current through a coil of wire, which generates a magnetic field around the coil.
when then universe was created?
for apex its: a quantum field, a gravitational field
Changes in the sun's magnetic field can lead to increased solar flares and coronal mass ejections, which can impact Earth's magnetic field, causing geomagnetic storms and disruptions in communication and navigation systems. Additionally, variations in the sun's magnetic field can affect the sun's overall brightness and lead to changes in solar activity cycles.
Earth's magnetic field is created by the movement of molten iron and nickel in the outer core of the planet. This movement generates electric currents, which in turn produce the magnetic field that surrounds Earth.
