An inductor may store energy in

Options

A. its electric field
B. its coils
C. its magentic field
D. Both in electric and magnatic field

Explanation

To solve the question "An inductor may store energy in what?", we can follow these steps:

### Step 1: Understand the Function of an Inductor
An inductor is a passive electrical component that stores energy in a magnetic field when electric current flows through it.

**Hint:** Recall the basic function of inductors in circuits.

### Step 2: Identify the Forms of Energy Storage
Energy can be stored in different forms, such as:
- Electric field
- Magnetic field
- Mechanical energy
- Thermal energy

**Hint:** Think about the types of energy associated with electric circuits.

### Step 3: Focus on the Inductor's Operation
When current flows through an inductor, it creates a magnetic field around it. The energy stored in this magnetic field can be expressed mathematically by the formula:
\[ U = \frac{1}{2} L I^2 \]
where \( U \) is the energy, \( L \) is the inductance, and \( I \) is the current.

**Hint:** Consider how the flow of current relates to the generation of a magnetic field.

### Step 4: Analyze the Options Given
The question provides options:
1. Electric field
2. Magnetic field
3. Both electric and magnetic fields
4. None of the above

From our understanding, the inductor primarily stores energy in the form of a magnetic field.

**Hint:** Eliminate options that do not align with the function of an inductor.

### Step 5: Conclusion
Based on the analysis, the correct answer is that an inductor stores energy in the form of a magnetic field.

**Final Answer:** The correct option is **C: Magnetic field**.
