A magnet of length 10 cm and dipole moment `1.44 Am^2` is placed on a horizontal surface in such a manner that its north pole is pointing towards the geographical north. Where will be the null point located from the centre of wire? Assume the horizontal component of Earth's magnetic field as `18muT` .

Explanation

To find the location of the null point from the center of the magnet, we will follow these steps:

### Step 1: Understand the Given Data
- Length of the magnet, \( L = 10 \, \text{cm} = 0.1 \, \text{m} \)
- Dipole moment, \( m = 1.44 \, \text{A m}^2 \)
- Horizontal component of Earth's magnetic field, \( B_H = 18 \, \mu T = 18 \times 10^{-6} \, T \)

### Step 2: Determine the Half Length of the Magnet
