All the magnets we know of yet, have two ends, a north pole and a south pole.
So each end of a magnet will attract poles of the opposite polarity, and will repel poles of similar polarity.
Some math suggest the existence of monopoles, but these have yet to be discovered. But they are sometimes good fodder for sci-fi.
What else can I help you with?
Will a magnet stick to a carbon rod?
No, carbon is not magnetic so a magnet will not stick to a carbon rod.
Can electricity pass through copper rod?
Yes, electricity can pass through a copper rod as copper is a good conductor of electricity due to its high conductivity properties. The electrons in a copper rod are able to move freely, allowing electricity to flow through it easily.
Why copper rod cannot be charged?
Because Copper is a conductor and conductors do not hold electricity. The charge flows out. But, A copper rod can be charged if it is in a rubber handle. This will result in the charge staying in the rod, thus charging it.
Does a copper rod increase in mass when heated?
Only an insignificant amount, due to mass-energy equivalence - the added energy implies some added mass.
How can you charge copper rod by holding it and rubbing it?
By rubbing the copper rod with a cloth or your hands, you transfer electrons between the rod and the fabric through friction. This process creates a build-up of static charge on the surface of the rod, giving it a net positive or negative charge.
What are the three important parts of electro magnet?
Battery/iron rod/copper wire.
How are electro magnet different from permanent magnet?
Electro magnets differs from permanent magnet because it requires electricity. A simple electro magnet consists of an iron rod wrapped in a coil of copper and when electricity flows through the copper, a magnetic field is formed.
How do you make a magnet by banging and hitting?
By striking the side of the end of a steel rod with a hammer you will make a weak magnet.
What is copper rod?
it is a rod made of copper
Will rod magnet still become a magnet when it cut across into thin slices?
yes.when you slice a rod magnet it will still be considered as a magnet
How can you determine the magnet if you have one brass rod and another magnet in space?
Cut one in half, and see if the two bits attract or repel one another. If they do, you have cut the magnet. Otherwise the rod. If you are allowed other equipment, you don't need to cut anything. Make a coil, connect to a meter, and see which rod, when pushed in and out of the coil, induces a current.
Will a magnet stick to a carbon rod?
No, carbon is not magnetic so a magnet will not stick to a carbon rod.
Would increasing the length of a rod in an electromagnet increase it's magnetism?
No, as in this case,the rod is the magnet,and the strength of a magnet does not depend on its size.
You are in a room where there are no objects except for two iron rods Only one of them is a magnet How can you identify the magnet?
Take a rod and touch with its end the middle of the second rod. If they move closer to one another, then you have a magnet in your hand. The real magnet has a magnetic field at its poles, but not in its center. So, as mentioned earlier, if you take the iron bar and touch its tip to the magnet's center the iron bar will not be attracted. This assumes that the magnet's poles are at its ends. There's no way you can identify which one is the magnet, 'cause there's no magnet in the room, only two iron rods. Tie your shirt or belt or sock etc. in the centre of rod and dangle it loosely and the magnet should point North quicker and more obvious than the non active rod
When you heat a copper rod does it increases its mass?
Heating a copper rod does not change its mass. However, the density of the copper rod may change slightly due to thermal expansion, which can cause the dimensions of the rod to increase.
Which is a to make a steel rod into a magnet?
To turn a steel rod into a magnet, you can use a process called magnetization. This can be done by rubbing the rod with a strong magnet in one direction, aligning the magnetic domains within the steel. Alternatively, you can place the steel rod in a strong magnetic field, such as that produced by an electromagnet, which will also align the magnetic domains and create a permanent magnet.
Where is the magnet train at?
