Solution

Step 1: Formula used

The angle of dip, δ=tan-1BvBh

Where,

Bv is the vertical component of the earth's magnetic field.

Bh is the horizontal component of the earth's magnetic field.

Here,

Bv=Bh

Step 2: Finding the angle of dip

By using the formula, we get

δ=tan-1(1)=45°

Therefore, the angle of dip at a place where the horizontal component of the earth's magnetic field is equal to the vertical component is 45°.
