...... 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.
A magnet in a speaker helps create sound by interacting with an electric current to move a diaphragm, which produces vibrations that create sound waves.
Electric currents can create a magnet by running through a coil of wire, which generates a magnetic field. This process is known as electromagnetism.
The best procedure to create a permanent magnet is to expose a ferromagnetic material to a strong magnetic field for an extended period of time, aligning the magnetic domains within the material to create a permanent magnetic field.
One way to create a permanent magnet is by aligning magnetic domains in a ferromagnetic material by exposing it to a strong magnetic field and then cooling it to set the alignment. Another method involves rubbing a piece of iron or steel along a magnet to align the domains in the material and create a weak permanent magnet.
A magnet can create electricity through electromagnetic induction. When a magnet moves near a conductor, such as a wire, it creates a changing magnetic field around the conductor. This changing magnetic field induces a current to flow in the wire, generating electricity.

Yes. That peculiar action weill create a current in the coil for as long as you keep the magnet moving.
it uses electricity to create a magnet
Rub a magnet with another metal...
it uses electricity to create a magnet
An electrical current will flow in a conductor, when a magnet is moved next to a conductor - or when the conductor is moved next to the magnet.
A magnet in a speaker helps create sound by interacting with an electric current to move a diaphragm, which produces vibrations that create sound waves.
Yes, you will create a temporary magnet. EX: if you put and nail next to an iron magnet, the nail will be temporarly magnetic.
Electric currents can create a magnet by running through a coil of wire, which generates a magnetic field. This process is known as electromagnetism.
If you use DC, you will create a magnet, and quickly kill your battery. If you use AC, you will not create a magnet, and possibly trip a circuit breaker. In either case, you're likely to create a large, noisy spark before you're through.
To create a captivating ferrofluid display, you will need a clear container, a strong magnet, and ferrofluid. Place the ferrofluid in the container and use the magnet to manipulate the fluid into mesmerizing shapes and patterns. Experiment with different movements and positions of the magnet to create a visually stunning display that will captivate viewers.
Hitting a magnet with a hammer can disrupt its alignment of magnetic domains, potentially weakening its magnetic field. However, it will not create a new magnetic field.
