Moving a conductor through a magnetic field a voltage is induced in the conductor is called what type of induction?
Moving a conductor through a magnetic field will produce alternatinc current (AC).
What are 3 factors which affect the magnitude of magnetic force on current-carrying conductors?
Electric current, magnetic field intensity, length of the conductor, angle between the electric current and magnetic field
When a compass is placed near a conductor where current flows its needle would deflect what does this indicate?
This proves that a magnetic field is developed around the conductor wen current flows through it...
Does the magnetic field increase or decrease if the current is decreased?
An increase in an electrical current will cause magnetism to increase but a decrease in an electrical current will cause magnetism to decrease.
Explain what happens when a long straight conductor is moved through a uniform magnetic field at a constant velocity Assuming that the conductor moves perpendicularly to the field?
Interesting question. Because Fleming's right hand rule tells us that a conductor carrying a current perpedicular to a magnetic field will move in a particular direction we know that movement, current and magnetic field are related. So if we take the current away and instead force the conductor to move as described then we would observe a current in the wire. However, you have not said that your conductor is connected in a circuit - in which case the charge carriers in the conductor will tend to one side like a bar magnet.AnswerThe original answer is incorrect. A voltage would be induced into the conductor. No current would flow unless the conductor forms a continuous circuit.
If an electrical current passes through a conductor what two things are generated?
If an electrical current passes through a conductor, there is an induced voltage (because no conductor has perfectly zero ohms), resulting in power dissipation, and there is a magnetic field, which can interact with other conductors in the vicinity of the first.
What is the magnetic effects of electrical current?
When an electrical current flows through a conductor, it creates a magnetic field around the conductor. This phenomenon is known as electromagnetism. The strength of the magnetic field is directly proportional to the current flowing through the conductor.
How does an water make an electrical generator work?
When a conductor of electricity moves through a stationary magnetic field, an electric current is induced in the conductor. A hydroelectric generator uses flowing water to spin an axle that is wrapped in conductive wires in a strong magnetic field. Current is generated in the wires, and that current is directed into the electrical grid. The actual process is somewhat more complex but that's the basics. The inverse is also true - when a stationary conductor is placed in a changing magnetic field, current is generated in the conductor. This is how an antenna works - radio waves generate a changing magnetic field which creates electrical current in the conductive antenna which is directed into the electronics in the radio where it is amplified so you can hear it.
How does electromagnetic induction produce induced current?
Before you can understand how electrical energy is supplied by your electric company, you need to know how it is produced. A magnet and a conductor, such as a wire, can be used to induce a current in the conductor. The key is motion. An electric current is induced in a conductor when the conductor moves through a magnetic field. Generating an electric current from the motion of a conductor through a magnetic field is called electromagnetic induction. Current that is generated in this way is called induced current. To induce a current in a conductor, either the conductor can move through the magnetic field or the magnet itself can move.
What happens when an electrical current runs through a conductor?
When an electrical current runs through a conductor, electrons flow in the direction of the current. This flow of electrons creates a magnetic field around the conductor. The amount of current flowing through the conductor is directly proportional to the strength of the magnetic field produced.
How does a magnet affect the electrical current?
A magnet can induce an electrical current in a conductor by creating a magnetic field that causes electrons to move. This phenomenon, known as electromagnetic induction, is the basis for how devices like generators and transformers work. The strength of the magnetic field and the motion of the magnet will impact the amount of current generated.
How do you increase the magnetic force in a current carrying coil or conductor?
To increase the magnetic force in a current-carrying coil or conductor, you can increase the current flowing through it, increase the number of loops in the coil, or use a material with higher magnetic permeability around the coil. These methods will strengthen the magnetic field generated by the coil or conductor.
How do moving electrical charges create magnetic fields?
When electrical charges move through a conductor, they create a magnetic field around the conductor as a result of electromagnetic induction. This is described by Ampère's law in electromagnetism, which states that a current-carrying conductor produces a magnetic field that circulates around it. The strength of the magnetic field is proportional to the current flowing through the conductor.
How is the movement of electrons in a conductor related to the formation of magnetic field?
When electrons move through a conductor, they create a flow of electrical current. This flow of current generates a magnetic field around the conductor in accordance with Ampere's law. The strength of the magnetic field is directly related to the magnitude of the current and the distance from the conductor.
A wire cannot cause a magnetic field if what?
A wire cannot cause a magnetic field if there is no current flowing through it. Magnetic fields are generated by the flow of electric current in a conductor.
What is the process in which electrical current is generated by placing a wire in magnetic field?
electromagnetic induction
How can the magnetic field produced around a current carrying conductor be detected?
The magnetic field produced around a current carrying conductor can be detected using a magnetic compass, a Hall effect sensor, or a magnetometer. These devices can detect the direction and strength of the magnetic field generated by the current flowing through the conductor.
