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 is a magnet that is creadted from electric current through a wire?
Electro-Magnet
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. . .
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
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.
What makes the pickup guitar make sound?
A guitar pickup is wire coiled around a magnet. When the string vibrates, it causes the magnet to vibrate, which creates an electric current in the wire. The signal created by that electric current is then fed into the amplifier which converts it to sound.
How can electricity be used to make a magnet?
Any time there is ANY flow of electric charges (any current), the current will be surrounded by a magnetic field.
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.
Will there be an induces electric current if the magnet remains at rest?
No, there will be no induced electric current if the magnet remains at rest relative to the conductor. Movement or a change in magnetic field is required to induce an electric current in a nearby conductor through electromagnetic induction.
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.
