Answer 1

Question :

What is the magnitude force per unit lengh on a wire carrying a current of 8A and making an angle of 30° with the direction of a uniform magnetic field of 0.15 T ?

AnSwer :

Current in the wire, I = 8A.

Magnitude of the uniform magnetic field, B = 0.15T

Angle between the wire and magnetic field,θ = 30°

Magnetic froce per unit lengh on the wire is given as :-

➠ f = BIsinθ

➠ f = 0.15 × 8 × 1 × sin30°

➠ f = 0.15 × 8 × 1/2

➠ f = 0.15 × 4

➠ f = 0.6 Nm$\sf ^{-1}$

Thus, the magnetic froce per unit Length on the wire is 0.6 Nm$\sf ^{-1}$
