Magnetic Flux Formula and Concepts

$B + A \times \cos(\theta)$

$B - A \times \cos(\theta)$

$B \times A \times \cos(\theta)$ (correct)

$B \div A \times \cos(\theta)$

When a current flows through a wire placed in a magnetic field

When a magnet is moved towards a coil

When there is no magnetic field in a given region (correct)

When a coil is perpendicular to the magnetic field

Increases the magnetic flux

No effect on the magnetic flux

Decreases the magnetic flux (correct)

Makes the calculation of magnetic flux impossible
