What is the effect on the direction of the compass needle when you close the circuit?
When you close the circuit, a magnetic field is produced which can deflect the compass needle. The direction of the compass needle will align with the magnetic field produced by the current flowing through the circuit.
What is the process of current in a circuit by changing a magnetic field?
When a magnetic field around a conductor is changed, it induces an electromotive force (EMF) in the conductor. This EMF causes a current to flow in the circuit, known as electromagnetic induction. The current will only flow when the magnetic field is changing, as stated by Faraday's law of electromagnetic induction.
What is a circuit which produces a magnetic field by an electrical current called?
That would be an electromagnet. It consists of a coil of wire through which an electric current passes to generate a magnetic field.
How does electricity create a magnetic field?
When electricity flows through a wire, it creates a magnetic field around the wire. This is because the moving electric charges generate a force that causes the magnetic field to form.
What induced voltage opposes the motion that causes it according to .?
Lenz's Law states that the induced voltage in a circuit will create a magnetic field that opposes the change in magnetic flux that caused it. This is to ensure that the original source of the changing magnetic field does not have its energy absorbed or dissipated.

How it can be possible to produce electric current in a uniform magnetic field?
-- Form a continuous circuit out of a conducting material. -- Move the conductor through the magnetic field, at an angle to the magnetic 'lines of force'.

Is a circuit a path made for magnetic field?
A circuit is a path for charge particles -- it conducts current. An inductor, a circuit component, generates a magnetic field, when an AC is on. ======================
What causes a magnetic field to be produced around a wire?
Current flows through a wire and produces a magnetic field.
How is mechanical force produced on a wire when it is passed through a wire in a magnetic field?
The movement through a magnetic field will induce a voltage; if there is a closed circuit, that will produce a current. The current, in turn, will have a magnetic field, which will interact with the external magnetic field. The direction of the interaction will be such that energy is conserved, i.e., it will tend to slow the wire down.
How does electricity create a magnetic field?
When electricity flows through a wire, it creates a magnetic field around the wire. This is because the moving electric charges generate a force that causes the magnetic field to form.
What is the leading theory for what causes earth's magnetic field?
The Dynamo Theory it what causes Earth's Magnetic Field
How did electricity and magnetisnm work to gether?
When electricity flows through a circuit then magnetic field is created around it
Is the magnetic field that is near an electrical circuit parallel or perpendicular to the circuit?
Perpendicular to the circuit.
Can you make an electrical current with an electrical field?
No. only flow of current develops electrical field. whereas magnetic field can make current to flow through a closed path. Absolutely YES. I wander how radios and TV works.AnswerYes, it is an electric field that causes current to flow in a circuit.
