Parts of molten rock at mid-ocean ridges are Magnetic minerals.

Further Explanations:

Mid-ocean ridges are defined as the seafloor mountain formed by the tectonic movement of the plates found in depth of 2,600 meters. And can rise up to 2km above the deepest ocean basin. This process takes place at the divergent plate boundary. The rate at which the spreading of the seafloor takes place concludes the morphology of the crest and width of the ocean basin. The new seafloor and the oceanic floor thus formed is the result of plate separation and mantle upwelling. The molten magma rises up from the faults in the form of lava and then form a new oceanic crust which on cooling forms lithosphere.

Magnetic mineral that have erupted during the volcanic eruption can be defined as the mineral that have magnetic properties. These minerals are generally obtained from the lava that has erupted during the volcanic eruption. These magnetic minerals also have the tendency to create a magnetic field around the region where it exists.

Magnetic minerals

Explanation:

 The magnetic minerals are the part of the molten rock at the mid ocean ridge and a few minerals that are pulled into the given magnetic fields just when warmed.

The magnetic field is a zone incorporating a magnet or electrical flow that can pull in or repulse certain articles put in the field. Various types of para- magnetic minerals are heated then they become strongly magnetic.

Therefore, Magnetic minerals is the correct option.
