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.
How can a magnet be used to create an electric current?
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.
Is not a permanent magnet?
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.
How is an electromagnet different from a regular bar magnet?
An magnet is a material or object that creates a magnetic field. Bar magnets constantly create their magnetic field, while electromagnets are coils that only produce a magnetic field when an electric current passes through it.
How can a magnet be used to create an electric current using the words magnetic field attract repel magnetic poles?
A magnet cannot use words to create an electric current. A moving magnet will induce electric current in adjacent conductors. This is usually described in terms of the rate that magnetic flux lines connecting the opposite poles of the magnet "cut" the conductors. The more flux lines cutting the conductors per second, the more current induced.
What controls the strength of a magnet made with electric current?
The strength of a magnet(electromagnet) made by flowing electric current through a conducting coil depends on magnitude of current. . .
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.
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.
What is a magnet that is creadted from electric current through a wire?
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 a temporary magnet made using electric current usually running around a metal core?
An electromagnet is a temporary magnet made using electric current running around a metal core. The magnetic field can be turned on and off by controlling the flow of current. Electromagnets are commonly used in various applications such as electric motors, MRI machines, and speakers.
What is a magnet created when electric current flows through a coil of wire?
A magnet created when electric current flows through a coil of wire is called an electromagnet.
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
Hans christian Oerested made the hypothesis that when an electric current flowed through a wire it acted like a?
magnet
What is the definition of eletro magnet?
A magnet that becomes energised when an electric current is passed through it.
How can a magnet be used to create an electric current?
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.
When does a magnet induce an electric current in a wire coil?
A magnet induces an electric current in a wire coil when there is a relative motion between the magnet and the coil, which generates a changing magnetic field. This changing magnetic field induces an electromotive force, leading to the flow of an electric current in the wire coil.
