Question

The magnetic flux linked with a vector area `vecA` in a uniform magnetic field `vecB` is ______.

विकल्प

• `vecB xx vecA`

• AB

• `vecB * vecA`

• `B/A`

Answer 1

The magnetic flux linked with a vector area `vecA` in a uniform magnetic field `vecB` is `bbunderline(vecB * vecA)`.

Explanation:

Magnetic flux is a scalar quantity defined as the dot product of the magnetic field vector and the area vector. It represents the total magnetic field lines passing through a given area.

`phi = vecB * vecA`

In terms of magnitudes and the angle (θ) between the two vectors, it can also be written as:

Φ = BA cos(θ)
