What else can I help you with?
Would it be good to visit a planet with a magnetic field?
We are already on a planet with a magnetic field and yes magnetic fields are what protect the planet from various dangers. Not to mention nearly every planet we have seen has a magnetic field (save venus). It is believed that the magnetic fields of planets save them from solar winds which would otherwise slowly strip the atmospheres of planets by taking out chunks of atoms every time they hit. Mars has an extremely weak (or none according to many scientists) magnetic field and as such the solar winds bash into it and scoop out ions from the planet. Overall conclusion: Yes, you want to visit a planet with a strong magnetic field, it's basically more protection (in theory at least).
Is there magnetism on every planet?
No. Mars has no magnetic field. Which is probably why it has no atmosphere either. The magnetosphere protects us from the solar radiation, which would otherwise knock our atmosphere off.
Imagine a planet with no mangetic field such a planet probably does not have a?

Is Venus a permanent magnet?
No.-----The earth has an important magnetic field.No, Earth would lose its magnetic field if its molten iron core were not moving. Scientists speculate that Mars had a magnetic field a long time ago but lost it when the planet cooled to the point that its core solidified.
How is the force affected when the current is reversed in a magnetic field?
The magnetic field would reverse.

How would a bar magnet orient itself relative to this planet and magnetic field?
A bar magnet would align itself with the Earth's magnetic field in a north-south direction. One end of the bar magnet would point towards the magnetic north pole while the other end points towards the magnetic south pole. This alignment is due to the interaction between the magnetic field of the planet and the magnetic properties of the bar magnet.

If the earth rotated more slowly would you expect it to have as strong a magnetic field?
No it would probably weaken. The Earth's magnetic field is due to a combination of two factors: Earth's relatively high iron content and Earth's relatively high rotation speed. If you reduced either factor you should expect the magnetic field's strength to be reduced.
Why would the earth cease to exist without the earths magnetic field?
There are certain high-energy particles electrically charged particles that are emitted from the sun and travel toward our planet. These particles are called Cosmic Rays. If they were allowed to strike the earth, they would kill all life on the planet. However, the earth's magnetic field deflects the vast majority of these particles, keeping them from hitting the planet. If the magnetic field was too small, it would not deflect enough of these Cosmic Rays. If the field was too strong, it would deflect the cosmic rays, but it would cause a deadly magnetic storm that would make life impossible!

What is the value of earth magnetic field?
The magnetic field of planet Earth is very important for sustaining life. The magnetic field creates a magnetic map around the world, which birds use to navigate. Also do they create the magnetic north and south pole. But the most crucial thing about our magnetic field is that it protects our atmosphere from solar activity, otherwise our atmosphere would be blown away by solar wind and everything on this planet would die. This happened to Mars, which had oceans and rivers and an atmosphere billions of years ago, but when it's core dried up, it lost it's magnetic field by which the atmosphere was vulnerable and blown away. Causing the planet too become freezing cold and all water to vanish.

What would Earth's magnetic field look like if it were solid, and why would it appear that way?
If Earth's magnetic field were solid, it would appear as a continuous, unbroken shell surrounding the planet. This is because a solid magnetic field would create a uniform and consistent barrier around Earth, similar to a protective shield.
