    The dip angle, also known as the magnetic inclination, is the angle between the horizontal plane and the total intensity vector of the Earth's magnetic field. It is denoted by the symbol δ.

    In this case, the dip angle is given as 30°.

    To find the magnetic field strength, we can use the formula:

    B = H / cos(δ)

    where B is the magnetic field strength and H is the horizontal component of the Earth's magnetic field.

    Since the magnet is freely suspended and oscillates in the horizontal plane, it aligns itself with the horizontal component of the Earth's magnetic field. Therefore, the magnetic field strength is equal to the horizontal component.

    Let's assume the horizontal component of the Earth's magnetic field is denoted by H0.

    Now, we can rearrange the formula to solve for H0:

    H0 = B * cos(δ)

    We are given that the bar magnet makes 20 oscillations per minute at the place where the dip angle is 30°. This means that the time period of each oscillation is 1/20 minutes.

    The time period (T) of an oscillation can be related to the magnetic field strength (B) and the magnetic moment (m) of the bar magnet using the formula:

    T = 2π * √(I / (B * m))

    where I is the moment of inertia of the bar magnet.

    In this case, we are not given the moment of inertia or the magnetic moment of the bar magnet, so we cannot directly calculate the magnetic field strength or the horizontal component of the Earth's magnetic field.
