Is the median the center of balance of triangle?
Yes and no. Each median divides the triangle into two such that for any point on the median, the mass on one side is balanced by the mass on the other. But the mass ahead of that point may or may not balance the mass behind. It is the point of intersection of the medians - the centroid - which is the centre of mass or centre of balance of the triangle.
Why the imaginary lines of magnet never intersect?
If they would intersect, that would mean that at one point in space, the field lines point to two different direction simultaneously. A compass needle would have to point to two different directions at once.
How does a compass use magnetism?
A compass would not work without a magnet. Inside the compass is a magnet which moves to line up with the Earth's natural magnetism. The north pole of the magnet is attracted to the south pole of the Earth. As such, the magnet moves to always be lining up in this way. When you use a magnet, you can see this in action as the needle moves around to always point northward and from knowing this, you can tell which way you are facing.
What is the difference between points and coordinates?
A point is a zero-dimensional object. It has no length, width, height, etc. Coordinates are the numerical location of that point. Point A can be at the coordinates (2,3) on a Cartesian grid.
Why every clock shown the time 10 10?
The time 10:10 is used for clocks in advertisements because it is considered visually attractive; it is balanced and the hands point upward.
Where does a compass point when it is moved close to a magnet?
That depends on which pole of the magnet it is moved close to. If it is brought close to the "South" pole of the magnet, the "North" pointer of the compass will be attracted to the magnet. If it is brought close to the "North" pole of the magnet, the "North" pointer of the compass will be repelled and will point AWAY from the magnet, while the "South" end of the compass pointer will point to the magnet.
How can you create a magnet?
...... rub a needle/other piece of metal against a magnet? I know that if you do that with a needle, then put the needle on top of some water, it will spin to point north.
All compasses point where?
A compass is a simple device which consists of a small, lightweight magnet which is balanced on a nearly frictionless pivot point. A compass will always point towards the North Pole because of the Earthâ??s magnetic field because the magnet inside the compass is drawn to that magnetic field.
How can the polarity of a magnet be determined?
Use a compass. It will always point to a magnet's south pole.
Which of the following can be done to demagnetize a permanent magnet?
heating the magnet past the Curie point
If there was a magnet beside a compass would the compass point to the north or south?
because inside of the earth acts like a big magnet and the magnet points to the north
What is the melting point of magnet?
Depends on what it is made of.
Does a freely suspended magnet always point in the north south direction?
Yes. A freely suspended magnet always point in the north south direction.
What causes the magnetic compass to react with a magnet?
The compass needle is a small bar magnet balanced on a pin. It swivels freely on this balance point. This is how it can align with the magnetic field of the Earth to show what direction magnetic north is. When you introduce another magnetic field, like from a magnet in close proximity, the needle will align with these local fields since their field strength is stronger than Earth's magnetic field - locally.

What causes the magnet compass to react with a magnet?
a compass works by detecting the earths magnetic field. a magnet also has amagnetic field just not as big so the compass needle points at the magnet ratherthan towards north.Another AnswerThe compass needle is a small bar magnet balanced on a pin.

What Three properties of a magnet?
1. Magnets attract iron and other ferromagnetic materials such as neodymium and cobalt. 2. Magnets attract or repel other magnets. 3. In addition one part of a magnet will always point north when allowed to swing freely.
