Answer 2

Given: A conductor of length 20cm carries current of 1A with magnetic

field of 4T that experiences a force of 0.4N.​

To find: The angle between conductor and magnetic field.

Solution:

• According to the magnetic field formula,

        $F = IlBsin$θ

• Here, f is the force experienced by the conductor, I is the current carried by the conductor, l is the length of the conductor, B is the magnetic field and θ is the angle between the conductor and the magnetic field.
• The length is given 20 cm, that is, 0.2 m.
• So,

        $0.4 N = 1A * 0.2 m * 4 T * sin$θ

        $\frac{0.4}{1*0.2*4} = sin$ θ

         θ $= sin^{-1} (0.5)$

            $= 90^{o}$

Therefore, the angle between conductor and magnetic field is 90°.
