Is it possible (and practical) to use electromagnetic waves to heat copper (or other metals such as iron, steel or an aluminium alloy) over long distances (such as 1km)?

EM waves heat copper by transferring energy to the atoms in the copper. The atoms absorb the energy and start to vibrate, which causes an increase in temperature.
Typically, high-frequency EM waves such as microwaves or radio waves are used to heat copper. These waves have enough energy to excite the atoms in the copper and cause heating.
No, EM waves tend to heat copper unevenly. This is because different parts of the copper may absorb different amounts of energy from the waves, leading to uneven heating.
The efficiency of using EM waves to heat copper depends on various factors such as the frequency and intensity of the waves, the properties of the copper, and the environment. In general, it is a relatively efficient method of heating compared to other techniques such as using flames or electric currents.
Yes, there are safety concerns to consider when using EM waves to heat copper. High-frequency EM waves can be harmful to human health, so it is important to use protective equipment and follow safety guidelines when working with them. Additionally, there is a risk of fire if the copper becomes too hot and can ignite nearby materials.
