Question

An 8 N force acts on a rectilinear conductors of 20 cm long placed perpendicular to magnetic field.
Determine the magnetic field induction if the current in the conductor is 40 A.

Answer 1

Answer:

Explanation:

Given force, F=8N

Length of conductor l=20cm=0.2m

Current in conductor, I=40A

Now, magnetic field B=?

Using F=BIl

⟹B=  

Il

F

=1T

⟹  

B

=1 Tesla
