Sea floor spreading / plate tectonics. Also magnetic reversal in the past.
when pressure builds under the plates they move in opposite directions.
Rocks formed at mid-ocean ridges exhibit patterns of magnetic stripes that record Earth's magnetic reversals. As magma rises and solidifies at the ridge, iron-rich minerals align with the Earth's magnetic field, locking in a record of the magnetic orientation at that time. When a magnetic reversal occurs, new rocks forming at the ridge will display the opposite magnetic alignment, creating a symmetrical pattern of alternating magnetic orientations on either side of the ridge. This evidence supports the theory of seafloor spreading and provides a timeline of Earth's magnetic history.
The magnetic fields of opposite charges appear as circular loops around each charge. The direction of the magnetic field lines is counterclockwise for positive charges and clockwise for negative charges when viewed from above. The strength of the magnetic field decreases as the distance from the charge increases.
Magnetic objects are attracted to a magnet because of the properties of the magnetic field. When a magnetic object is brought near a magnet, the magnetic fields interact in a way that leads to attraction. This attraction occurs due to the alignment of magnetic domains within the object, causing it to be pulled towards the side of the magnet with the opposite polarity.
When a north magnetic pole is brought near a south magnetic pole, they attract each other. This attraction occurs because opposite magnetic poles (north and south) naturally pull towards one another, similar to how opposite charges attract in electricity. This principle is fundamental to magnetism and is utilized in various applications, including compasses and magnetic devices.
The opposite of magnetic attraction is magnetic repulsion.
true
True. Bands of magnetic material in the sea floor that have opposite poles or exhibit magnetic reversal provide evidence for sea floor spreading. This is because as new oceanic crust forms at mid-ocean ridges, Earth's magnetic field periodically reverses, creating magnetic stripes on the ocean floor that align with the direction of the magnetic field at that time.
Repellent or repulsive. Those words are opposites of magnetic.
This is a "proof by contradiction", where the evidence would fail to support the reverse assumption, giving credence to the original hypothesis.

An antithesis.

Rocks that exhibit magnetism opposite to the current magnetic field are referred to as antiferromagnetic or diamagnetic. This means that the magnetic moments of the atoms or ions within the rock align in such a way that they oppose the external magnetic field applied. Antiferromagnetic materials have equal but opposite magnetic moments whereas diamagnetic materials create a magnetic field opposite to the external field.
When opposite charges are brought together, the magnetic field is not affected. Magnetic fields are produced by moving charges, not static charges. So, bringing opposite charges together will not change the magnetic field in the vicinity.
