What else can I help you with?
What is a magnet that is creadted from electric current through a wire?
Electro-Magnet
What causes the magnet to rotate in dynamo?
The rotation of a magnet in a dynamo induces a changing magnetic field, which in turn induces an electric current in the surrounding wire coils due to electromagnetic induction. This current produces electrical power that can be harnessed for various applications.
Why there is an induced current in a coil when a bar magnet is thrust out of the coil?
The magnetic lines of force surrounding the bar magnet, cut through the coils of wire, causing electrons to move. This induces an electric current. It is the movement that is important, whether moving into, or out of, the coil.
What is a magnet formed by electricity called?
Electromagnet. This is a type of magnet which the magnetic field is produced by the flow of electric current through wires generally surrounding a metal or iron core. Electric motors, generators, relays, loudspeakers, hard disks are examples of Electromagnets in other equipment.
A magnet can generate an electric current in a wire if the magnet is close enough to the wire and if the magnet is also?
strong
Can a magnet stop an electric current?
A magnet cannot stop an electric current, but it can influence the flow of the current. Moving a magnet near a wire carrying an electric current can induce a voltage in the wire, which can affect the behavior of the current.
Does a magnet use an electric charge?
lol the term "magnet" means energy.
How can a magnet induce current in a wire?
When a magnet moves near a wire, it creates a changing magnetic field around the wire. This changing magnetic field induces an electric current to flow in the wire through electromagnetic induction. The current is only induced while there is a relative motion between the magnet and the wire, or if the magnetic field intensity changes.
What is true about the magnet if an electric field exists around a magnet?
Then the magnet not only has magnetism, but also an electrical charge.
What kind of magnet is a magnet made from a steel paper clip?
If it has been magnetized by another magnet, then it is just a temporary magnet, but if it uses an electric current, then it is an electro-magnet.
How does an electric current make a magnet?
the electric current is generated by the electric field. thus by the left hand rule when current is passed through a conductor a magnetic field is generated around it so that it is a similar act of a magnet. thus it seems to be a magnet.
What is the definition of eletro magnet?
A magnet that becomes energised when an electric current is passed through it.
