convection is heat transfer through high temp to lower temp with the help of fluid medium.ex:heat exchangers
Infrared heating uses electromagnetic waves to directly heat objects, while convection heating relies on the circulation of air to transfer heat. Infrared heating is more efficient and heats up quickly, while convection heating is slower but provides more even heating throughout a space.
convection
Heating by radiation is when heat energy is transferred through electromagnetic waves, such as from the sun to the Earth. Heating by convection, on the other hand, is the transfer of heat through the movement of a fluid like air or water. In convection, warmer fluid rises and cooler fluid sinks, creating a cycle of heat transfer.
In a kettle, convection works by heating water at the bottom of the kettle. As the water gets hot, it becomes less dense and rises to the top, displacing the cooler water. This creates a circular flow of water as hotter water rises and cooler water sinks, leading to even heating of the entire volume of water in the kettle.
Convection works best in fluids like air and water, where temperature differences lead to density variations and create fluid motion. It is commonly seen in the Earth's atmosphere, oceans, and in heating systems like radiators and hot air balloons.

The heating alone is not, no, but the convection it sets up, thus forming winds and weather systems, is a valid example.
