Name any two devices in which electromagnets are used.

Explanation

### Step-by-Step Text Solution

1. **Understanding Electromagnets**:
- An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. When electric current flows through a coil of wire wrapped around a ferromagnetic material (like iron), it creates a magnetic field, magnetizing the material.

2. **Identifying Devices that Use Electromagnets**:
- There are various devices that utilize electromagnets for their functioning. Two common examples are:
- **Electric Bell**: An electric bell uses an electromagnet to create sound. When the current flows through the coil, it magnetizes the iron armature, which then moves and strikes a bell, producing sound.
