Fill in the following blanks with suitable words :
An electric current flowing in a wire produces a ________ effect.

Answer

To fill in the blank in the statement "An electric current flowing in a wire produces a ________ effect," we can follow these steps:

1. **Understand the Concept**: Recall that electric current is the flow of electric charge through a conductor, such as a wire. When this current flows, it can create various effects.

2. **Identify the Effects of Electric Current**: There are several effects caused by electric current, including heating effects, chemical effects, and magnetic effects.

3. **Focus on the Relevant Effect**: In this context, we are particularly interested in the effect that is commonly associated with electric currents in wires, which is the magnetic effect.

4. **Fill in the Blank**: Based on our understanding, we can conclude that the blank should be filled with the word "magnetic."

Thus, the completed statement is: "An electric current flowing in a wire produces a **magnetic** effect."
