We produce electric field and magnetic field. If we change the electric field with time (so magnetic field alse change), required frequency, then we produce electromagnetic wave.
yes, electromagnetic wave is a radio wave
Sound Wave
Frequency
Solar energy.
em wave is generated by photons which emitter the energy in the form of light
many people uses an electromagnet when working.
An electromagnet can attract conductor pins because when current flows through the coil of the electromagnet, a magnetic field is generated. This magnetic field induces a temporary magnetism in the conductor pins, causing them to be attracted to the electromagnet.
Primary wave is a wave which is directly generated from source and secondary waves are generated from p-waves.

increase the strength of the magnetic field generated by the electromagnet. This is because more current will flow through the electromagnet, resulting in a stronger magnetic field. However, it is important to ensure that the electromagnet can handle the increased current to prevent overheating or damage.
Objects were attracted to the electromagnet because the electric current running through the coil generated a magnetic field. This magnetic field magnetized the objects, causing them to be pulled towards the electromagnet.
If the current stops flowing through an electromagnet, the magnetic field that was being generated will also disappear. This will cause the electromagnet to lose its magnetic properties and no longer attract or repel magnetic materials.
