A wire, of mass m = 0, 2 kg and length l = 0.5m, current I = 2A and "floats" horizontally in a homogeneous magnetic plane with horizontal dynamic lines perpendicular to the wire. Calculate the magnetic flux density in the wire. Given g = 10 m / s ^ 2.

Respuesta :

We have the next data

m=0.2 kg

l=0.5m

I=2A

g=10m/s^2

The formula that we will use the next formula to calculate the force

[tex]F=m\cdot a=0.2\cdot10=2[/tex]

where F is the force and a =g

Then for field strength

[tex]\begin{gathered} F=B\cdot l\cdot I \\ \end{gathered}[/tex]

We substitute the values

[tex]2=B\cdot0.5\cdot2[/tex]

Then we isolate the B

[tex]\begin{gathered} 0.5B=\frac{2}{2}=1 \\ B=\frac{1}{0.5}=\text{ 2T} \end{gathered}[/tex]

ANSWER

B=2T
