What else can I help you with?
Can an electric current exert a force on a magnet?
In a conductor - only if the field is moving, thus changing.
A magnet is useful in generating electricity because a magnetic force moves?
through a wire coil to induce an electric current in a process known as electromagnetic induction. As the magnet moves relative to the coil, the changing magnetic field creates an electric current. This current can then be harnessed to generate electricity.
What is the classical explanation of a dc electric current in a metallic wave?
A changing magnetic field always produces an electric field, and conversely, a changing electric field always produces a magnetic field. This interaction of electric and magnetic forces gives rise to a condition in space known as an electromagnetic field.
Does a moving magnetic field produce an electric current?
Yes, a moving magnetic field can induce an electric current in a conductor, according to Faraday's law of electromagnetic induction. This phenomenon is the basis for many applications of electrical generators and transformers.
What causes a electric current in a electric circuit?
Voltage causes current to flow in an electric circuit.
What does an electric current Carry?
Electric current carries electric charge. Actually to say it in the right sense, we have to say that electric current is the rate of flow of electric charges
The current that flows in an electric circuit carries what?
Current Carries Negatively charged electrons.
What do you call a material that carries an electric current?
A Conductor.
A substance that carries an electric current when dissolved in water is called?
Electrolyte
What is a word for a coil of wire that carries an electric current?
The word is "solenoid".
A carries electric current easily while an does not?
A material that carries electric current easily is called a conductor, while a material that does not is called an insulator. Conductors have free electrons that can move easily in response to an electric field, allowing the flow of current. Insulators have tightly bound electrons that do not move easily, preventing the flow of current.
A moving magnet produces an electric current is this true?
A changing magnetic field produces an electric current, so yes. This is true.
What are 3 ways to change characteristics of a magnetic field by an electric current?
By changing the magnitude of the current flowing through the conductor. By changing the direction of the current flow in the conductor. By changing the orientation or shape of the conductor carrying the current.
What does a changing magnetic field induce in a conductor?
A changing magnetic field induces an electric current in a conductor.
What is it called when you measure of how much electrical energy carries electrons?
Electron flow is current, or coulombs per second. Electron potential is voltage or joules per second.
How does a magnetic field make a electic current?
A changing magnetic field induces an electric current in a conductor, according to Faraday's law of electromagnetic induction. This is because the changing magnetic field creates an electric field that causes charges to move within the conductor, generating an electric current.
Can an electric current generate an electromagnetic wave?
Not a constant electric current but a changing one will generate electromagnetic waves.First: If you have a lone electron, and it is accelerated in any way, it will send off an electromagnetic wave. This is because a changing electric field generates a magnetic field.It is also true that changing magnetic field will generate an electric field. This is the reason that if you have an electric current, which is generating a magnetic field, and you change the current you generate an electromagnetic wave. To generate a continuous sinusoidal electromagnetic wave you continuously change the current sinusoidally.
