What if Earth was exposed to a huge magnetic field?

In summary: The magnetic field would kill us almost instantly. In summary, exposure to a magnetic field of 10^10 teslas for about 1 second would be lethal and result in instant death. The impact of a moving magnetic field vs a stationary one would likely just result in different effects on objects in its path. It is uncertain how much time we could be exposed to such a field without dying, but it is safe to say that it would be a matter of seconds.

What would happen if the entire Earth was somehow exposed to a massive magnetic field, such as those found near magnetars, like 10^10 teslas, for about 1 second? Would everyone instantly die? What would be the impact of a moving magnetic field vs a stationary magnetic field be? How much time could we be exposed to that kind of field without dying?

According to wikipedia, the effects of a magnetic field of that strength would be lethal. See here: https://en.wikipedia.org/wiki/Magnetar#Magnetic_field

It's probably a safe bet to say that everyone would be dead in under a second.

Course disruption to Earth's spin over putting us back in ice age and most probably killing us

You can levitate a frog with just 16 Tesla.

It would become much harder to open the door of your refrigerator.:oops:

If you go from zero to ginormous to zero in a second, I'd be worried about the induced electric fields. Zap!

As has already been pointed out, that's irrelevant because we would be dead LONG before that happened.
 

FAQ: What if Earth was exposed to a huge magnetic field?

1. What would happen if Earth was exposed to a huge magnetic field?

If Earth was exposed to a huge magnetic field, it would significantly affect the planet's magnetic field. This could potentially lead to changes in the Earth's climate, weather patterns, and even the protection of our atmosphere from harmful solar radiation.

2. How would a strong magnetic field affect life on Earth?

A strong magnetic field could potentially disrupt the navigation systems of animals that rely on the Earth's magnetic field for migration or finding their way. It could also impact the magnetic orientation of some plants and insects.

3. Would a strong magnetic field affect technology on Earth?

Yes, a strong magnetic field could have a significant impact on technology. It could disrupt electronic devices, satellites, and communication systems that rely on precise magnetic measurements.

4. Can a strong magnetic field cause earthquakes or volcanic eruptions?

There is currently no scientific evidence to suggest that a strong magnetic field can directly cause earthquakes or volcanic eruptions. However, it could potentially affect the Earth's tectonic plates and contribute to geological activities.

5. Is it possible for Earth to be exposed to a huge magnetic field?

Earth is already exposed to a magnetic field due to its molten iron core. However, it is unlikely for Earth to be exposed to a significantly stronger magnetic field unless there is a major change in the planet's core or a significant external force acting on the planet.
