Consider the following statements As one moves from one place to another, the magnetic field of the earth will vary
(1) in magnitude
(2) in direction
(3) linearly with height
(4) linearly with the temperature of the place.
Of these statements

Options

A. 1 and 2 are correct
B. 3 alone is correct
C. 1, 2,3 and 4 are correct
D. 3 and 4 are correct

Explanation

To solve the question regarding the variation of the Earth's magnetic field as one moves from one place to another, we will analyze each statement one by one.

### Step 1: Analyze the first statement - "in magnitude"
The magnetic field of the Earth does indeed vary in magnitude depending on where you are located on the Earth's surface. For example, the magnetic field strength is generally stronger at the poles and weaker at the equator. Therefore, this statement is **correct**.

### Step 2: Analyze the second statement - "in direction"
The direction of the Earth's magnetic field also changes as you move from one location to another. At the equator, the magnetic field lines are horizontal, while at the poles, they are vertical. Hence, this statement is also **correct**.
