Magnetic Flux Linkage

• What is the term used for the quantity commonly used for solenoids?

  Magnetic flux linkage
• How does the number of coils in a wire affect the induced e.m.f?

  More coils mean a larger e.m.f is induced
• What is the formula for magnetic flux linkage?

  ΦN = BAN
• What does Φ represent in the equation for magnetic flux linkage?

  Magnetic flux in Weber (Wb)
• What are the units of magnetic flux linkage?

  Weber turns (Wb turns)
• What happens to the magnetic flux when the angle θ is 0 degrees?

  Magnetic flux is maximum
• What is the condition for minimum magnetic flux?

  When cos(θ) = 0, θ = 90 degrees
• What induces an e.m.f in a circuit?

  Change in magnetic flux linkage over time
• What are the factors that cause an induced e.m.f?

  Changing magnetic flux density, area, or angle
• How does the magnetic flux through a rectangular coil change with angle?

  It decreases as the angle decreases
• What is the equation for the component of flux density that is perpendicular?

  ΦN = BAN cos(θ)
