A square loop of wire with a side length of 10 cm is kept in a 1.2-T magnetic field. Determine (i) the magnetic flux through the loop if the plane of the loop is perpendicular to the field lines, (ii) the angle θ in the equation for the flux, Φ = B⋅A⋅cos(θ), if the loop is at an angle of 45° with the field lines as shown in the figure below (iii) the magnetic flux through the loop at this position of the loop.

• A. (i) 0.012 Wb (ii) θ = 45° (iii) 8.5 × 10^-3 Wb
• B. (i) 0.012 Wb (ii) θ = 90° (iii) 2.2 × 10^-3 Wb
• C. (i) 0.038 Wb (ii) θ = 45° (iii) 2.2 × 10^-3 Wb
• D. (i) 0.038 Wb (ii) θ = 90° (iii) 8.5 × 10^-3 Wb
