A Magnetic Force
Uranus NOVEL STARS ANSWER: None of these
no. Eris does not have a magnetic field
Magnetic field is made up of magnetic lines.
A magnet creates a magnetic field. This field is a force that affects magnetic objects. Like any other force, it can be used to move objects.
Like a doughnut
Opposites attract, like charges repel each other.

A Magnetic Force
Have you ever seen a magnet? Did you see the field? There you go. While you can't see the field itself directly, you can see the effects of the field if you use iron filings or something like that; they'll line up with the magnetic field lines
Something NOT LIKE Earth!

No, the Earth's Magnetic Field acts just like a BAR Magnetic. It has a North and South Pole and its magnetic lines of its force field are more tightly 'compressed' near the Poles than at the Equator. See the image below for an example, or Google "magnetic field lines".
Uranus NOVEL STARS ANSWER: None of these
a photon cannot be deflected by an electric or magnetic field because it has no charge and no magnetic poles like elementary particles such as the electron
no. Eris does not have a magnetic field
Because it is far too small to have any effect. The Earth's magnetic field is thought to be generated thousands of miles underground by moving rivers of iron.
