Which direction does a freely suspended magnet point to?
A freely suspended magnet always rests in the north-south direction because the magnetic south pole of the earth lies in the geographic north direction and the magnetic north pole of the earth lies in the geographical south direction.
Why does a freely suspended magnet?
A freely suspended magnet point in the north south direction because the north pole of the magnet is attached to the South pole of the Earth and the South pole of the Magnet is attached to the North pole of the Earth. This is the reason why a freely suspended magnet point in the north south direction.
What will a suspended bar magnet do?
When you suspend it freely, the magnet aligns itself so that the north pole points towards the magnetic north pole of the earth.
Why does a freely suspended magnet not show exact geographic North and South?
A freely suspended magnet does not show exact geographical South and North because the magnetic axis and geographical axis of the Earth do not coincide.
What happens to the suspended magnet?
Answer. When the North Pole of a magnet is brought near the South Pole of a freely suspended magnet, the North Pole attracts the South Pole of the freely suspended magnet because unlike poles attract each other and like poles repel each other.
What happens when a soft magnet is brought near to a permanent magnet?
Answer. Answer: when a magnetic material or a soft magnet is brought near a permanent magnet an opposite polarity is developed across the material that is the end which is close to the north pole will have south pole and vice versa.
Why does magnet always point to North?
We use these names because if you hang a magnet from a thread, the magnet’s north pole points (almost) towards the north direction. This is because the Earth’s core (its centre) is a large, weak magnet. Your little, strong magnet lines up with Earth’s magnetic core, so it points north.
Which ends of a magnet are attracted to which ends of another magnet?
Magnets can also attract each other, but only if they face in opposite directions. A magnet has two ends called poles; one end is the north pole and the other is the south pole. A north pole will attract a south pole; the magnets pull on each other. But the two north poles will push each other away.
What are the two ends of a magnet called?
The end that faces the north is called the north-seeking pole, or north pole, of the magnet. The other end is called the south pole. 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.
Can I cut a magnet?
You can cut the magnet with a saw, following the line of cut, but you can also use a diamond-plated cutter in a lathe and, once placed, press it in place. You can also use a chisel on the line of cut that you have made on the magnet.
At what temperature do magnets demagnetize?
around 80 °C
Can a watch demagnetize itself?
Anything that becomes magnetised can slowly become demagnetised without intervention. However, a watch could remain magnetised for months or years, keeping it from functioning properly. Fortunately, demagnetising a watch is often a simple process.
Can you demagnetize a watch?
For the pulse type, put the watch on the demagnetizer, push the button, then rotate the watch 90 degrees, and push the button again. This type of demagnetizer emits a pulse of rapidly decaying strength. So it automatically disrupts the magnetic field in the watch and thus demagnetize the watch.
What is the best way to demagnetize a magnet?
Demagnetize a Magnet by Heating or Hammering You can get the same effect by repeatedly hammering a magnet, applying pressure, or dropping it on a hard surface. The physical disruption and vibration shake the order out of the material, demagnetizing it.
Why does heating a magnet demagnetize it?
How it Works. Excessive heat causes atoms to move more rapidly, disturbing the magnetic domains. As the atoms are sped up, the percentage of magnetic domains spinning in the same direction decreases. This lack of cohesion weakens the magnetic force and eventually demagnetizes it entirely.
Can you ever have a monopole magnet?
To date, no one has ever found a magnetic monopole in nature – we’ve never found a magnet that is truly north or truly south. “While we can find electric monopoles in the form of charged particles, we have never observed magnetic monopoles.”
