The strength of an electromagnet depends on the strength of the· _ _ flowing through it and the number of _ of the wire

Explanation

To solve the question, we need to fill in the blanks regarding the factors that affect the strength of an electromagnet.

### Step-by-Step Solution:

1. **Understanding Electromagnet**: An electromagnet consists of a coil of wire, usually wrapped around a core material (often soft iron). When electric current flows through the wire, it generates a magnetic field.

2. **Identifying the Factors**: The strength of the electromagnet depends on two main factors:
- The strength of the electric current flowing through the wire.
