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 force on Earth is called Earth's magnetic field or also the geomagnetic field.
Scientists believe Jupiter has a liquid metallic hydrogen core which allows it to form a strong magnetic field. Trapped magnetic particles form radio waves which are amplified by the planet's many moons and which are released into space.

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

The presence of a magnetic field indicates that a planet may have a liquid outer core made of iron and nickel. This liquid outer core generates the planet's magnetic field through a process called dynamo action. The magnetic field helps protect the planet from solar wind and cosmic radiation.
Most importantly to us, the earth has a permanent magnetic field.
