What are 3 ways to induce an electric current in a wire?
You can induce an electric current in a wire by moving a magnet near the wire, passing a current through a nearby wire, or changing the magnetic field around the wire.
What is the concept of self-inductance of wire and how does it affect the behavior of electrical circuits?
Self-inductance is a property of a wire where it creates a magnetic field around itself when current flows through it. This magnetic field can induce a voltage in the wire itself, which can affect the behavior of electrical circuits by causing delays in the flow of current and changes in voltage levels.
Can you make electicity from a magnet?
No, magnets alone cannot generate electricity. However, when a magnet is moved near a coil of wire, it can induce an electrical current in the wire through the process of electromagnetic induction. This principle is the basis for how many electric generators work.
How can you induce current in a wire using a permanent magnet?
By moving the wire perpendicular to the magnetic field lines created by the permanent magnet, you can induce a current in the wire through electromagnetic induction. The changing magnetic field as the wire moves induces an electric field, resulting in a current flow in the wire according to Faraday's law.
Does a neutral wire carry current in an electrical circuit?
Yes, a neutral wire carries current in an electrical circuit.

What does a changing magnetic field induce?
An electrical current.

What is the difference between a line wire and a load wire in electrical wiring?
A line wire carries electrical current into a device, while a load wire carries electrical current out of a device.

Yes, a neutral wire carries current in an electrical circuit.
How can you use a magnet to induce a current?
You can induce a current in a wire by moving the magnet in and out of the coil or by moving the coil near the magnet. The changing magnetic field created by the moving magnet induces a current in the wire according to Faraday's law of electromagnetic induction.
What is the flow of current through a wire known as?
The flow of current through a wire is known as electrical current.
What is produced when a magnetic field moves relative to a closed wire loop?
Faraday says you will induce a current in the wire.
What is the magnetic field that is produced around a wire when an electrical current flows through it?
When an electrical current flows through a wire, it creates a magnetic field around the wire.
What are the differences between a load wire and a hot wire in electrical circuits?
In electrical circuits, a load wire carries the electrical current to the device being powered, while a hot wire supplies the electrical current to the circuit. The load wire is connected to the device, while the hot wire is connected to the power source.
