Electromagnetic waves are related to the vibrations of an electrical charge or magnetic field. These waves consist of synchronized oscillations of electric and magnetic fields that propagate through space at the speed of light. This allows them to travel through a vacuum like space.
What else can I help you with?
Where is the magnetic field created alternator?
The magnetic field in an alternator is created by the rotor, which is an electromagnet that produces a rotating magnetic field as it spins. This magnetic field induces an alternating current in the stator windings through electromagnetic induction, which is then converted to usable electrical power.
Can electrical currents in a circuit produce thermal energy light sound and magnetic forces?
Yes to all. -- Electrical current in a toaster produces thermal energy, often known as "heat". -- In a light bulb produces light. -- In the wires dangling from eaqr-buds produces sound. -- In a solenoid coil or motor stator produces magnetic forces.
How do moving electrical charges create magnetic fields?
When electrical charges move through a conductor, they create a magnetic field around the conductor as a result of electromagnetic induction. This is described by Ampère's law in electromagnetism, which states that a current-carrying conductor produces a magnetic field that circulates around it. The strength of the magnetic field is proportional to the current flowing through the conductor.
What is the purpose of the coil in a speaker?
The coil in a speaker, often called the voice coil, is used to convert electrical signals into mechanical vibrations (sound). When an electrical current passes through the coil, it interacts with the magnetic field of the speaker, causing the coil to move back and forth rapidly, which in turn creates sound waves.
What energy does stereo produces?
A stereo system produces sound energy by converting electrical signals into vibrations through speakers. These vibrations produce sound waves that travel through the air and can be heard by our ears.
Why all electrical machines works on electromagnetic principle but not on electrostatic principle?
it works on the electromagnetic principle the conductor cuts the magnetic field which produces induces emf for the flow of current
Can electrical wiring interfere with cell phone reception?
Electrical wiring with current flowing through it produces an electromagnetic field. That magnetic field can interfere with other electromagnetic radiation, such as the radio signal that are produced and received by a cellular phone.
Does lightning produces magnetic field?
Yes, The movement of electrical charges produces a magnetic field
Where is the magnetic field created alternator?
The magnetic field in an alternator is created by the rotor, which is an electromagnet that produces a rotating magnetic field as it spins. This magnetic field induces an alternating current in the stator windings through electromagnetic induction, which is then converted to usable electrical power.
How are EM waves formed?
When electrical charges get accelerated then it produces a kind of disturbance both electrical and magnetic in two perpendicular directions varying sinusoidally with time. The electrical vector and magnetic vector both will be perpendicular to the direction in which disturbance is propagating. Hence the electromagnetic wave is termed as transverse wave.
Can electrical currents in a circuit produce thermal energy light sound and magnetic forces?

What is an electrical current that produces a magnetic field?
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
