Dielectric heating

Okay kiddo, so have you ever seen a toy car that has a remote control? Well, that remote control sends signals to the car through invisible waves called electromagnetic waves. It's like a magic signal that travels through the air!

Now, imagine that instead of a toy car, we have food or something we want to cook. We can use electromagnetic waves, like the ones from the remote control, to heat up the food!

But how does that work? Well, first we need something called a dielectric material. This is something that can't conduct electricity very well, but it can be affected by electromagnetic waves. One common example is a plastic container like Tupperware.

When we put our food in the plastic container and put it in the microwave, the electromagnetic waves create an electric field around the food. This field makes the molecules inside the food start to move around and rub against each other, creating friction. That friction creates heat, which cooks the food!

Pretty cool, huh? So, dielectric heating is just using electromagnetic waves to heat up something that's inside a dielectric material, like a plastic container. It's like using magic waves to cook our food!
