The magnetic force on Earth is called Earth's magnetic field or also the geomagnetic 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).
The magnetic fields are not aligned with the rotational axis of the planet and they are not located at the center of the planet.
Mars has a magnetic field.
Large deposits of iron ore within the planet generate the planet's magnetic field.for protection

All planets have magnetic fields. I believe that in most cases, this magnetic field can act as a shield.

A planet needs to have a magnetic field in order to have auroras.
