An engineer is designing a circular coil with 200 turns, each having a radius of 5 cm. When he applies an electric current of 3 A to the coil, he needs to determine the strength of the magnetic field at the centre of the coil. Using the formula for the magnetic field of a coil, what is the resultant value of the magnetic field generated at the coil's centre?a.
The strength of the magnetic field at the centre of the coil is 2.4π × 10⁻³ T.
b.
The strength of the magnetic field at the centre of the coil is 1.2π × 10⁻³ T.
c.
The strength of the magnetic field at the centre of the coil is 3.6π × 10⁻³ T.
d.
The strength of the magnetic field at the centre of the coil is 2.4π × 10⁻² T.
e.
The strength of the magnetic field at the centre of the coil is 2.4π × 10⁻⁴ T.

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.
