You get a magnetic field whenever a current flows through a wire,
you get an electromagnetic field whenever the current changes.
Run a varing current into a wire of correct length (about a quarter of a wave-length)
and you have an antena. (that's the way radios & TVs work)
An electrical field generates a magnetic field in nearby metals - wrapping a piece of magnetic material in electrically conductive wire then passing current through it will generate a magnetic field. An easy way to do this is to wrap coated copper wire around an iron core. With DC current the field is either on (pulling) of off (not pulling), with AC current the field is generated and removed multiple times per second - each time the poles being reversed. Beware, as a coiled wire in series with a capacitor and power supply can generate radio waves, an electromagnet with AC power can generate the same waves (back and forth magnetic fields.)
the conductor is placed in between the magnets,the dc supply is given to the these magnets to make a electromagnets and intial motion is given to the conductor manually or electrically to cut the flux automatically emf will be induced
I am trying to find out what the uses for Electromagnetism.
All electric currents create a magnetic field.
An electromagnetic wave is the result of an oscilating, or accelerating, electric charge.
By designing and making equipments where coupling of electricity and magnetism play vital role in that equipment
For example, you use light to see; radio waves for radio and television transmissions; microwaves for communications, but also to heat food.
u don't
the energy that makes the electromagnetic spectrum is electromagnetic radiation
Microwaves because we use them everyday
Through Radiation
what does an electromagnetic spectrum consist of
electromagnetic waves are longitudinal (like a slinky).
electromagnetic
Energy
Like, electromagnetic energy? Please specify what you mean.
Convert electrical energy to energy of motion...
A microwave oven uses electrical energy (which is electromagnetic energy) from the mains, and it generates microwave energy (which is also electromagnetic energy) to heat/cook food items.
That energy is called "electromagnetic waves" or "electromagnetic energy".
the energy that makes the electromagnetic spectrum is electromagnetic radiation
A battery changes chemical energy into electric (electromagnetic) energy.
Light is a form of electromagnetic energy.
Electromagnetic energy travels in waves.
I would call it an electromagnetic wave, or electromagnetic energy.
Energy from the Sun, Electromagnetic energy.
