Questions & Step-by-Step Solutions
A coil with 100 turns and an area of 0.01 m² is placed in a magnetic field of 0.5 T. What is the magnetic flux through the coil?
Step 1: Identify the formula for magnetic flux, which is Φ = B * A * N.
Step 2: Identify the values given in the question: B (magnetic field) = 0.5 T, A (area) = 0.01 m², and N (number of turns) = 100.
Step 3: Substitute the values into the formula: Φ = 0.5 T * 0.01 m² * 100.
Step 4: Calculate the product: 0.5 * 0.01 = 0.005, then 0.005 * 100 = 0.5.
Step 5: The result is Φ = 0.5 Wb (Webers), which is the magnetic flux through the coil.
Magnetic Flux – Magnetic flux (Φ) is the product of the magnetic field (B), the area (A) through which the field lines pass, and the number of turns (N) in the coil.
