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.
No, carbon is not magnetic so a magnet will not stick to a carbon 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.
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.
Only an insignificant amount, due to mass-energy equivalence - the added energy implies some added mass.
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.
Battery/iron rod/copper wire.
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.
By striking the side of the end of a steel rod with a hammer you will make a weak magnet.
it is a rod made of copper
yes.when you slice a rod magnet it will still be considered as a magnet
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.
No, carbon is not magnetic so a magnet will not stick to a carbon rod.
No, as in this case,the rod is the magnet,and the strength of a magnet does not depend on its size.
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
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.
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.
