<reasoning>

Identify the physical scenario

The question asks for the primary force acting on a floating object.

Analyze the given options

  • Magnetism is an electromagnetic force between magnetic poles.
  • Buoyancy is the upward force exerted by a fluid that opposes the weight of a partially or fully immersed object.
  • Tension is a pulling force transmitted through a string, rope, cable, or wire.
  • Torsion is the twisting of an object due to an applied torque.

Select the correct force

Buoyancy is the primary upward force that allows an object to float in a fluid.
