Magnetization (M) is the product of the magnetic field intensity (H) and the magnetic susceptibility (χ):

M = χH

Given:

χ = 3.7 × 10^-3

H = 10^4 A/m

M = (3.7 × 10^-3) × (10^4 A/m)

= 37 A/m

Explanation

• The formula for the period of a pendulum is T = 2π√(l/g), where l is the length of the pendulum and g is the acceleration due to gravity.
• Since the mass and diameter are doubled, the acceleration due to gravity (g) on the planet will be half that of Earth.
• Therefore, the new period of oscillation will be √2 times the period on Earth, meaning if it was a second's pendulum on Earth, it will be 2√2 seconds on the planet.
