Answer:
The magnetic flux through a loop is zero when the B field is perpendicular to the plane of the loop.
Explanation:
Magnetic flux are also known as the magnetic line of force surrounding a bar magnetic in a magnetic field.
It is expressed mathematically as
Φ = B A cos(θ) where
Φ is the magnetic flux
B is the magnetic field strength
A is the area
θ is the angle that the magnetic field make with the plane of the loop
If B is acting perpendicular to the plane of the loop, this means that θ = 90°
Magnetic flux Φ = BA cos90°
Since cos90° = 0
Φ = BA ×0
Φ = 0
This shows that the magnetic flux is zero when the magnetic field strength B is perpendicular to the plane of the loop.
Answer:
D. depends just on the B field going through the loop
Explanation:
The magnetic flux trough a loop is given by the formula:
[tex]\Phi_B=\vec{B}\cdot \vec{A}[/tex]
[tex]\Phi_B=BAcos\theta[/tex]
Where B is the magnitude of the magnetic field and A is the area of the loop.
It is clear that the flux is maximum when the angle between the direction of B and the direction of the normal vector of A is zero (cos0 = 1).
Furthermore, we can notice that only the magnetic field that crosses the loop contributes to the flux.
Hence, the correct answer is:
D. depends just on the B field going through the loop
hope this helps!!
