1. By friction.
2. by magnetism
Electromagnetic waves are produced by the acceleration of electric charges. They have both electric and magnetic components, oscillating perpendicular to each other and to the direction of wave propagation.
They are driven by electric motors or by compressed air
name two effect produced by electric current.
By mixing hydroxide and sulfuric acid
Any electric charge undergoing acceleration will produce Electromagnetic waves. This is by far the most common way.If an oscillating electric field is synchronized with an oscillating magnetic field of exactly the same frequency a beam of light will be produce where the two fields are orthogonal in all dimensions.
Electrical charges can be transfered through friction and contract.
When electrons flow between two objects, a flow of electric current is produced. This movement of charges generates a magnetic field around the flow of current.
The electric force between two charged objects can be increased by increasing the magnitude of the charges on the objects or by decreasing the distance between the objects.
The electric field strength exactly midway between two equal charges is zero. This occurs because the electric fields produced by the two charges cancel each other out at that point due to their opposite directions.
The electric power supplied to a radio is used to produce two types of energy: heat and sound. The sound is the useful part, and work is always continuing to find ways of producing less heat, because it only uses up electric power, and there are much better ways to keep our hands warm.
No, hybrid and electric vehicles work two different ways. Hybrid uses fuel and electric, while the electric cars run on electricity alone. I recommend hybrid as I feel they are more efficient.
One way to produce an electric field is through the presence of charged particles. When charged particles, such as electrons or protons, are stationary or in motion, they generate an electric field around them. Another way to produce an electric field is through changing magnetic fields. According to Faraday's law of electromagnetic induction, a changing magnetic field induces an electric field, causing the flow of electric charges.
