Answer 1

Here you go,

Hope it helps!

Answer 2

75 Volts of EMF is being induced.

Given : A conductor of length 1meter moves at right angles to a uniform magnetic field flux density 1.5 Wb/m2 with a velocity of 50 m/sec.

To find : The EMF induced in the conductor.

Solution :

We can simply solve this numerical problem by using the following process. (our goal is to calculate the value of the induced EMF)

Here, we will be using the following mathematical formula.

EMF induced = B × l × v × sinθ

Where,

• B = Flux density
• l = Length of the conductor
• v = Velocity of the conductor
• θ = Angle between B and v

In this case,

• B = 1.5 Wb/m²
• l = 1 m
• v = 50 m/s
• θ = 90° (as, the conductor moves at right angles to a uniform magnetic field)

So, by putting the available data, we get :

EMF induced = 1.5 × 1 × 50 × sin 90° = 75 Volts

(This will be considered as the final result.)

Hence, 75 Volts of EMF is being induced.
