To make a magnet you can do it three ways.
No1. Get a metal rod and wrap some Insulated copper wire around it. You can use some other wires but it might not work as well. Make sure the wire isn't too thick. Wrap the wire 50+ times. Connect the two ends of the wire to a battery. Don't connect it to a strong power source as it will get very hot very quickly. Now the rod is a magnet until the battery dies or you cut off the current. Also; now the iron rod now has become a weak permanent magnet. The more current you add to it the more stronger it will be and the longer you have the battery on the stronger it will be.. Also, don't drop it as it will lose it's magnetic properties.
No2. Get a magnet. The stronger the better. Rub the magnet up a piece of metal then when you get to the end take the magnet off the metal and take it back to the start making sure the magnet doesn't touch the metal. I don't really like this method as it takes a long time to get the metal to pick up anything decent.
No3. Get a magnet and let it stick to a piece of metal. The piece of metal will be weak but enough to make the needle on a compass move.
(Don't ruin a compass. Mine point south-west and it shouldn't do that...)
An electromagnet is a magnet while an electric current is running through the coil. Turn off the current and it is no longer magnetised, and is, therefore, not a permanent magnet.
A permanent magnet is a material that maintains a persistent magnetic field without the need for an external power source. For example, "The refrigerator door securely closed thanks to the strong permanent magnet embedded in the seal."
a Temporary Magnet lose its magnetism quickly, a Permanent Magnet is hard and it keeps it magnetism
When you break a magnet, the regions where the break occurred become the new North and South poles. This is because the magnetic domains within the magnet align themselves in a way that creates these distinct poles at the broken ends.
Put it in a coil which has an alternating current in it. The AC current produces a magnetic field in the coil which alternates with the changing voltage. This changes the magnetism of the permanent magnet. Gradually reduce the current in the coil and the permanent magnet will end up unmagnetised.
You can rub a permanent magnet against something else that can be magnetized, like a paper clip.
A. Compasses typically use a permanent magnet.
To make a temporary magnet, you can rub a piece of iron or steel with a permanent magnet. This process aligns the magnetic domains in the material, creating a temporary magnetic field. To enhance the temporary magnetism, you can increase the number of times you rub the material with the permanent magnet.
Yes, it is a permanent magnet.
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
yes - need to run electricity through it to make it a linear magnetic generator.
To make a metal magnet, you can create a temporary magnet by stroking a metal material (like iron) with a permanent magnet in the same direction. This aligns the magnetic domains in the metal. For a more permanent magnet, you can heat the metal to a specific temperature and then cool it in the presence of a magnetic field to enhance its magnetic properties.
PermanentThere is no source of current in a compass, therefore the magnet is a permanent magnet.
When a magnet is attached to a permanent magnet, it can become temporarily magnetized by aligning its magnetic domains with the strong magnetic field of the permanent magnet. This alignment causes the magnet to exhibit magnetic properties for a short period of time.
Perminant magnet
The magnet in a compass is a permanent magnet. It retains its magnetism without the need for an external electrical current.
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
