What is the formula for magnetic flux (Φ_B)?
Understand the Problem
The question is asking for the magnetic flux formula, which relates to how much magnetic field passes through a certain area. Understanding the formula involves recognizing the key components such as the magnetic field strength and area involved.
Answer
Φ_B = B A cos(θ)
The formula for magnetic flux (Φ_B) is given by Φ_B = B A cos(θ), where B is the magnetic field strength, A is the area the magnetic field passes through, and θ is the angle between the magnetic field and the normal (perpendicular) to the surface.
Answer for screen readers
The formula for magnetic flux (Φ_B) is given by Φ_B = B A cos(θ), where B is the magnetic field strength, A is the area the magnetic field passes through, and θ is the angle between the magnetic field and the normal (perpendicular) to the surface.
More Information
Magnetic flux quantifies the amount of magnetic field passing through a surface. It is a scalar quantity and is typically measured in Weber (Wb) in the SI system.
Tips
A common mistake is mixing up the angle θ. Ensure it is measured from the normal to the surface, not the surface itself.
