Is it possible to transmit electricity as electromagnetic waves?
Well, when you transmit something as an electromagnetic wave, it is no longer an electric current, since an electromagnetic wave doesn't involve movement of charges. However, you can convert electrical energy into an electromagnetic wave, transfer that, and then convert it back to an electric current at the receiving end.
What type of energy provided by the lamp helps Jan read?
Electromagnetic energy, electrical lighting is one of the many ways electrical energy is used. Electric current flows in these devices when they are connected to batteries or plugged into an electric outlet. An electric device uses the electrical energy provided by the current flowing in the device.
What does a electromagnetic pulse can do to stop a wrist watch from ticking?
An EMP is as it sounds, a pulse of electromagnetic energy, this induces a very high current (thousands of volts) in parts of the watch, and since many electrical items, such as microchips, are very sensitive to high voltages, it causes them to break.
What is Elctromagnetic?
An electromagnet is created by winding a coil of wire around an iron core. Electrical current is passed through the wire, which creates a magnetic field. Something that is electromagnetic is anything that is an electromagnet.
What does not carry an electrical current?
An electrical insulator.
What surrounds every electrical current?
An electromagnetic field.
What is the process in which electrical current is generated by placing a wire in magnetic field?
electromagnetic induction
When and magnetic fields exist its called an electromagnetic field?
A temporary magnetic field created by a flowing electrical current is an electromagnetic field. Stop the current from flowing, it goes away.
When a electrical current is generated in a conductor by placing it in a magnetic field the process is known as?
Electromagnetic Induction

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.
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
A generator can transforms into?
Generator can transform mechanical energy into electrical energy by converting the rotational motion of its turbine into electrical current through electromagnetic induction.
What occurs because alternating electrical current flowing through a wire creates an electromagnetic field around the wire?
shorts
What energy is moving electrons?
Kinetic energy. If you consider a larger scale, i.e., the electrical current, this is usually called electrical energy.
Does all moving charges generate electromagnetic waves?
No, consider a coil of wire conducting a constant current. There will be a static magnetic field around it, but no electromagnetic waves with E X H = P
Under what circumstances can an electrical charges produce a magnetic field?
Faraday discovered that wire carrying a current, electrons, has an electromagnetic field around it.
