State whether the following statements are true or false :
An electromagnet is a temporary magnet.

Answer

To determine whether the statement "An electromagnet is a temporary magnet" is true or false, we can follow these steps:

### Step 1: Understand what an electromagnet is
An electromagnet is a type of magnet that is created when electric current flows through a coil of wire, often wrapped around a ferromagnetic material like iron.

**Hint:** Think about how electricity can create a magnetic field.

### Step 2: Identify the characteristics of an electromagnet
Electromagnets only exhibit magnetic properties when an electric current is flowing through them. When the current is turned off, the magnetic effect disappears.

**Hint:** Remember that the presence of electricity is crucial for the magnetism in an electromagnet.

### Step 3: Compare with permanent magnets
Permanent magnets, on the other hand, maintain their magnetic properties without the need for an electric current. They are made from materials that have a stable magnetic field.

**Hint:** Consider how permanent magnets differ from electromagnets in terms of their magnetic properties.

### Step 4: Determine the nature of electromagnets
Since electromagnets only work when electricity is applied and lose their magnetism when the current is stopped, they are classified as temporary magnets.

**Hint:** Reflect on the definition of temporary magnets and how it relates to the operation of electromagnets.

### Step 5: Conclude the statement
Based on the understanding that electromagnets are only magnetic when current flows through them, we can conclude that the statement "An electromagnet is a temporary magnet" is true.

**Final Answer:** True.

### Summary of Steps:
1. Understand what an electromagnet is.
2. Identify the characteristics of an electromagnet.
3. Compare with permanent magnets.
4. Determine the nature of electromagnets.
5. Conclude the statement.
