What is the formula for magnetic flux?
What is the formula for magnetic flux?
- $B + A \times \cos(\theta)$
- $B - A \times \cos(\theta)$
- $B \times A \times \cos(\theta)$ (correct)
- $B \div A \times \cos(\theta)$
In which situation is the magnetic flux zero?
In which situation is the magnetic flux zero?
- 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
How does increasing the angle between the magnetic field and the normal to the area affect the magnetic flux?
How does increasing the angle between the magnetic field and the normal to the area affect the magnetic flux?
- Increases the magnetic flux
- No effect on the magnetic flux
- Decreases the magnetic flux (correct)
- Makes the calculation of magnetic flux impossible
