Does a change in magnetic field induce an electric current?
Yes, a change in magnetic field can induce an electric current in a conductor, as described by Faraday's law of electromagnetic induction. When a magnetic field through a conductor changes over time, it creates an electromotive force, which leads to the generation of an electric current in the conductor.
Can an electric current be used to affect a compass needle?
Yes, an electric current can affect a compass needle because it creates a magnetic field. When the electric current flows through a wire, it generates a magnetic field around the wire, which can deflect the compass needle and change its direction.
Can an electric current generate an electromagnetic wave?
Yes, an electric current can generate an electromagnetic wave. When an electric current flows through a conductor, it creates a magnetic field around the conductor. This changing magnetic field then generates an electromagnetic wave, which consists of oscillating electric and magnetic fields propagating through space.
How do you change the direction of a magnetic field?
You can change the direction of a magnetic field by reversing the flow of electric current in a wire or by changing the orientation of a permanent magnet. Alternating the direction of current in a coil can also reverse the direction of the magnetic field it produces.
Electric current is induced when?
electric current is induced when a conductor (such as a wire) moves through a magnetic field or when there is a change in the magnetic field surrounding a conductor. This phenomenon is known as electromagnetic induction, discovered by Michael Faraday in the 1830s.
Does a change in magnetic field induce an electric current?
Yes, a change in magnetic field can induce an electric current in a conductor, as described by Faraday's law of electromagnetic induction. When a magnetic field through a conductor changes over time, it creates an electromotive force, which leads to the generation of an electric current in the conductor.
Does an electric current produces a magnetic field?
yes*edit: don't confuse moving with changing. A change in magnetic field strength/direction will induce an electric current.
Do magnetic effect of electric current causes a change in colour in a solution through which electric current is passed?
i don't believe it does
Can an electric current be used to affect a compass needle?
Yes, an electric current can affect a compass needle because it creates a magnetic field. When the electric current flows through a wire, it generates a magnetic field around the wire, which can deflect the compass needle and change its direction.
What most occur to produce electric current?
Chemical changes, change in magnetic flux linked with a conductor cause the production of electric current.
What is needed for electromagnetic induction?

What happen to magnetic compass if the current is changed?
If an electric current flows through a wire, it will create a magnetic field. ... a ship or an airplane, it can damage or otherwise change the ship's magnetic compass.
How do you change the direction of a magnetic field?
You can change the direction of a magnetic field by reversing the flow of electric current in a wire or by changing the orientation of a permanent magnet. Alternating the direction of current in a coil can also reverse the direction of the magnetic field it produces.

In an electromagnet as the electric current changes what happens to the magnetic field?
As the electric current changes in an electromagnet, the strength of the magnetic field also changes. An increase in current strength leads to a stronger magnetic field, while a decrease in current strength results in a weaker magnetic field. This ability to control the magnetic field strength makes electromagnets versatile in various applications.
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.
