# How Can You Generate A Current In A Wire?

wikihow.comImage: wikihow.comThe rotating coils of wires cut across the electromagnetic fields, thus generating electric current within the cable. The rotations can, however, be designed to either produce alternating current or direct current.

## How does an electric generator make a current?

Electric generators are devices that use alternating magnetic fields to create a current through a wire circuit. While full scale models can be complex and expensive to build, you can create a simple electric generator easily.

## How are magnetic fields created by a current carrying wire?

Magnetic field created by a current Magnetic field created by a current carrying wire. This is the currently selected item. What are magnetic fields? Magnetic force between two currents going in the same direction Magnetic force between two currents going in opposite directions Induced current in a wire

## How is the current from moving a wire determined?

Taking thissimple geometry, the electric currentin amperes generated from moving the wirethrough the magnetic field would be determined by the resistanceof the circuit to which you have itconnected, using Ohm's law, I = V/R.

## Why does a current produce an electric field?

Because a current-carrying wire (I assume that's what you are referring to) has no net charge (nor is there a changing magnetic field, assuming a constant current). If it were a current of just charge carriers without a wire--a beam of electrons in a vacuum chamber, for instance--then there would certainly be an associated electric field.

#### Can You Connect A Hot Wire To A Neutral Wire?

What happens if you connect a hot wire to a neutral wire? If the hot wire touches the metal casing, then the electricity will now flow through the ground wire instead. If the hot wire comes into contact with both the neutral and the ground, then it will flow through both wires back to the source but as the ground has less resistance more current will flow through it.

#### How Do You Secure A Wire?
