Question

a 8n froce acts on a rectilinear conductor of 20 cm long placed perpendicular of magnetic field dertermine the mangetic field induction if the current is 40 A​

Answer 1

Answer:

hello...

bro.....

this is your answer.......

The magnetic field induction is 1 Tesla

Explanation:

The formula for force acting on a conductor is given by

\boxed{F=BiL\sin\theta}

Given

Force acting on the conductor F = 8 N

Length of the conductor L = 20 cm = 0.2 m

Current in the conductor i = 40 A

Since the conductor is placed perpendicular to the magnetic field

Therefore, θ = 90°

From the above formula we get

B=F/(iL\sin\theta)

B=8/(40\times0.2\sin90^\circ)

\implies B=8/8=1\text{ Tesla}

Therefore, the magnetic field induction is 1 Tesla
