Questions & Step-by-Step Solutions
A solenoid has a length of 1 m and a cross-sectional area of 0.01 m². If the magnetic field inside it is 0.4 T, what is the magnetic flux?
Step 1: Identify the formula for magnetic flux, which is Φ = B * A.
Step 2: Determine the values needed for the formula. Here, B (magnetic field) is 0.4 T and A (cross-sectional area) is 0.01 m².
Step 3: Substitute the values into the formula: Φ = 0.4 T * 0.01 m².
Step 4: Calculate the result: 0.4 * 0.01 = 0.004.
Step 5: State the final answer: The magnetic flux is 0.004 Wb.
Magnetic Flux – Magnetic flux (Φ) is the product of the magnetic field (B) and the area (A) through which the field lines pass, measured in webers (Wb).
Solenoid Properties – A solenoid is a coil of wire that generates a magnetic field when an electric current passes through it, and its properties can be used to calculate magnetic flux.
