Answer 3

To find the force (Fa) in this scenario, we can use the formula for the magnetic force on a current-carrying conductor in a magnetic field:

$F = B \cdot I \cdot L$

where: F = Magnetic force (in Newtons) B = Magnetic field strength (in Tesla) I = Current flowing through the conductor (in Amperes) L = Length of the conductor (in meters)

Now, let's substitute the given values:

$B = 0.25 \, \text{T}$ $I = 2 \, \text{A}$ $L = 0.4 \, \text{m}$

Now, plug these values into the formula:

$F = 0.25 \, \text{T} \times 2 \, \text{A} \times 0.4 \, \text{m}$

$F = 0.25 \, \text{T} \times 2 \, \text{A} \times 0.4 \, \text{m} = 0.2 \, \text{N}$

So, the magnetic force (Fa) acting on the current-carrying conductor is 0.2 Newtons.
