Question

. Calculate the magnetic field if a force of 100 N acts on a straight conductor of 10 cm length perpendicular to it when 1 ampere current flows through it. *
2 points
a) 1 Tesla.
b) 10 Tesla.
c) 100 Tesla.
d) 1000 Tesla.
​

Answer 1

Answer:

c)100 telsa is the answer, but I don't know whether it is right or wrong.

Answer 2

Given Data :-

• Force experienced = 100 N
• Length = 10 cm = 0.1 m
• Current = I A
• θ = 90° (Since any value is given)

---------------------------------------------------------

To Find :-

Magnetic Field

--------------------------------------------------------

Solution :-

$\red{ \tt FORMULA} : \blue{ \boxed{ \orange{\tt F_B = (I) × (L) × (B) × sinθ }}}$

_________________________

Substituting the values we get ,

➱ 100 = I × 0.1 × B × sin (90°)

➱ 100 = I × B × 0.1

➱ B = 100 / ( I × 0.1 )

➱ B = (1000 /I )T
