# What does an electric current through a wire produce what affects the strength of what is produced?

Contents

When the electric current moves through a wire, it makes a magnetic field. If you coil the wire around and around, it will make the magnetic force stronger, but it will still be pretty weak. Putting a piece of iron or steel inside the coil makes the magnet strong enough to attract objects.

## What does an electric current through a wire produce?

If we run an electric current through a wire, it will produce a magnetic field around the wire. The direction of this magnetic field can be determined by the right-hand rule.

## Which is produced around a wire when an electrical current is in the wire quizlet?

When electric current flows through a conducting wire, a magnetic field is produced around the wire.

## What affects the strength of the electric current produced by a magnet?

The four main factors that affect the strength of an electromagnet are the loop count, the current, the wire size, and the presence of an iron core.

## What happens when an electric current passes through a wire How was that fact discovered?

How was this discovered? When an electric current passes through a wire, it creates a magnetic field around the wire. This was discovered by how Maxwell observed the connections between positive and negative electrical charges.

## What effect does passing current through a coil of wire have?

A current through any conductor creates a circular magnetic field around the conductor due to Ampere’s law. The advantage of using the coil shape is that it increases the strength of the magnetic field produced by a given current.

## What is the effect of electrons flowing through a coil of wire?

When current flows through a conductor such as a copper wire, all of those electrons that were previously moving about randomly get together and start moving in the same direction. A very interesting effect then happens: The electrons transfer their electromagnetic force through the wire almost instantaneously.

## What do you get when an electric current flows through the turns of a coil?

The coil becomes an electromagnet when a current flows through it. The armature supports the coil and can help make the electromagnet stronger. This makes the motor more efficient. There are two permanent magnets.

## When current flows through a wire a magnetic field is created around the wire?

When you run current through a wire, a circular magnetic field is created around the wire. It does not have poles but the magnetic field does have a direction (tangent to the circle. Keep in mind you have to use the right hand rule to find the direction).

## What is the process of creating electricity in a wire by passing the wire through a magnetic field?

What Is Electromagnetic Induction? Electromagnetic induction is the process of generating electric current with a magnetic field. It occurs whenever a magnetic field and an electric conductor, such as a coil of wire, move relative to one another.

## How does electricity produce Magnetism How does magnetism produce electricity?

Magnetic fields can be used to make electricity

Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current. Electricity generators essentially convert kinetic energy (the energy of motion) into electrical energy.

## Why does electric current produce magnetic field?

A magnetic field is generated by an electric current. While an electric charge is moving, this is possible. … The magnetic field is generated when the atom spins and orbits the nucleus. The direction of the magnetic field is also dictated by the direction of the electric charge’s spin and orbiting.

## What is created when a magnet moves through a coil of wires?

Electromagnetic induction

A magnet and a coil of wire can be used to produce an electric current. A voltage is produced when a magnet moves into a coil of wire. This process is called electromagnetic induction . The direction of the induced voltage is reversed when the magnet is moved out of the coil again.
