If the current is pointing into the page, the direction of the magnetic field will be upwards.
<h3>
What is direction of magnetic field?</h3>
The Maxwell right-hand thumb rule is used to indicate the direction of the magnetic field in the direction of the current or charge.
According to this rule, "if the thumb of the right-hand points along the direction of the current, then the remaining curled fingers of the same hand give the magnetic field direction due to the current".
Thus, when the current is pointing into the page, the direction of the magnetic field will be upwards.

The rate at which the height of the water in this cylindrical tank is increasing is 26.18 m/mn.
<h3>How to calculate the volume of a cylinder?</h3>
Mathematically, the volume of a cylindrical tank can be calculated by using this formula:
V = πr²h
Where:
Differentiating with respect to h, we have:
dV/dt = πr²(dh/dt)
3 = 3.142 × 5² × dh/dt
3 = 78.55dh/dt
dh/dt = 78.55/3
dh/dt = 26.18 m/mn.
