A coil is composed of 200 turns and is traversed by an electric current of 5 A. Which of the following statements is correct about the magnetic field generated by this coil?a.
The magnetic field generated by the coil is inversely proportional to the number of turns that compose it.
b.
The magnetic field generated by the coil is independent of the cross-sectional area of the core in which it is wound.
c.
The magnetic field generated by the coil is greater than if it had fewer turns.
d.
The magnetic field generated by the coil is directly proportional to the electrical resistance of the conductor wire that composes it.
e.
The magnetic field generated by the coil is directly proportional to the electric current flowing through it.

A solid object is fully submerged in a liquid with a density of 1200 kg/m³ at a depth of 8 metres. Given that the acceleration due to gravity is 9.81 m/s², let’s figure out how the pressure from the liquid on the object changes with depth and how this affects the total buoyant force acting on the object.
