8 Identify List three everyday devices that could not have been developed without the discovery of electromagnetism.

## Step 1<br />The question is asking for three everyday devices that could not have been developed without the discovery of electromagnetism. Electromagnetism is a fundamental concept in physics that describes the interaction between electrically charged particles and the electromagnetic field. This field is created by the movement of electrically charged particles.<br /><br />## Step 2<br />The discovery of electromagnetism has led to the development of many devices that we use in our daily lives. These include electric motors, generators, transformers, and many other electrical and electronic devices.<br /><br />## Step 3<br />The question asks for three such devices. The answer provided includes a refrigerator, a television, and a computer. These are all devices that rely on electromagnetism for their operation.<br /><br />## Step 4<br />The refrigerator uses an electric motor to run the compressor, which is a key component in the cooling process. The television uses an electric motor to run the tuner, which allows it to receive different channels. The computer uses an electric motor to run the hard drive, which stores all the data on the computer.
