Do negative magnets repel?
If it moves in the other direction, then the v value must be negative. These two particles repel each other if the magnetic forces determined by their respective magnetic fields between them cancel each other out by pointing in different directions away from one another.
What happens when you put two negative magnets?
When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another. This is similar to electric charges. Like charges repel, and unlike charges attract.
Do two positive magnets attract?
When two like-poles point together, the arrows from the two magnets point in OPPOSITE directions and the field lines cannot join up. … Unlike-poles attract: When a north pole and south pole point together, the arrows point in the SAME direction so the field lines can join up and the magnets pull together (attract).
What can magnets attract?
What Kind of Objects Are Attracted to Magnets?
- Magnetic Elements: Metals. Iron, nickel and cobalt are strongly attracted to magnets. …
- Magnetic Minerals. Certain minerals have attractions to magnetism, some weak, some very strong. …
- Alloys: Metal Mixtures. …
- Odd Everyday Things. …
- Aurora Borealis.
Why does magnet attract iron?
Magnets attract iron due to the influence of their magnetic field upon the iron. … When exposed to the magnetic field, the atoms begin to align their electrons with the flow of the magnetic field, which makes the iron magnetized as well. This, in turn, creates an attraction between the two magnetized objects.
What happens when a magnet is brought near a compass?
One end of any bar magnet will always want to point north if it is freely suspended. … In Experiment 1, when you bring the compass near a strong bar magnet, the needle of the compass points in the direction of the south pole of the bar magnet. When you take the compass away from the bar magnet, it again points north.
Can magnets repel metal?
When magnets are placed near each other, opposite poles attract and like poles repel one another. … That alignment dissipates once the magnetic field is removed and therefore, the only way for a metal to be repelled by a magnet is if it’s first magnetized to the opposite pole.
