The image above represents the magnetic flux density/field induction. To calculate the magnetic force of a field, four essential parameters are needed and the parameters are Magnetic Force (F), Quantity of Charge (q), Average Velocity of the Charge (v), and Angle between v and B (Î¸).

The formula for calculating the magnetic flux density/field induction:

B = ^{F} / _{qVsinÎ¸}

Where;

B = Magnetic Induction or Magnetic Flux Density

F = Magnetic Force

q = Quantity of Charge

v = Average Velocity of the charge

Î¸ = Angle between v and B

Let’s solve an example;

Find the magnetic flux density/field induction of a field when Magnetic Force (F) is 17, Quantity of Charge (q) is 21, the Average Velocity of the Charge (v) is 15, and Angle between v and B (Î¸) is 120Â°.

This implies that;

F = Magnetic Force = 17

q = Quantity of Charge = 21

v = Average Velocity of the charge = 15

Î¸ = Angle between v and B =Â 120Â°

B = ^{F} / _{qVsinÎ¸}

B = ^{17} / _{(21 x 15)(sin 120Â°)}

Then, B = ^{17} / _{(315)(0.866)}

B = ^{17} / _{(272.79)}

B = 0.0623

Therefore, the **magnetic flux density/field induction** is **0.0623 Tesla.**
