Inside a magnet, magnetic lines:

Options

A. do not exist
B. are from South pole to North pole
C. are from North pole to South pole
D. remain scattered

Explanation

To solve the question regarding the direction of magnetic field lines inside a magnet, let's break it down step by step.

### Step 1: Understanding Magnetic Poles
A magnet has two poles: the North pole and the South pole. The magnetic field lines are a representation of the magnetic field around the magnet.

**Hint:** Remember that every magnet has a North and a South pole, which are crucial for understanding the direction of magnetic field lines.

### Step 2: Direction of Magnetic Field Lines Outside the Magnet
Outside the magnet, the magnetic field lines travel from the North pole to the South pole. This is the standard convention for representing magnetic field lines.

**Hint:** Visualize the magnet and remember that the field lines always go from North to South when outside the magnet.

### Step 3: Direction of Magnetic Field Lines Inside the Magnet
Inside the magnet, the magnetic field lines actually travel from the South pole to the North pole. This completes the loop of the magnetic field lines.

**Hint:** Think of the magnetic field lines as forming a closed loop, which means they must return to the starting point, creating a continuous path.

### Step 4: Conclusion
Based on the above understanding, the correct answer to the question "Inside a magnet, magnetic lines:" is that they travel from the South pole to the North pole.

**Final Answer:** Inside a magnet, magnetic lines travel from the South pole to the North pole.
