Question

For all of your answers below, include units and make sure there is a space between the number and the units. Use 2 sigfigs and scientific notation. For example: 0.00518 Wb = 5.2E-3 Wb Determine the magnetic flux through a circular surface (a disk) of radius 1.0 cm in a uniform magnetic field of 0.01 T when: The surface is oriented perpendicular to the field (top): The surface is oriented with its area vector at an angle of 45 degrees to the field: The surface is oriented with its area vector perpendicular to the field (top):

Explanation / Answer

here,
radius of disk, r = 1 cm = 0.01 m
magnatic field, B = 0.01 T

magnatic flux = magantic field*area*CosA
Case1:
fi = BA*CosA
fi = 0.01*pi*0.01^2*Cos0
fi = 3.14*10^-6 wb

case 2:
fi = B*A*CosA
fi = 0.01*pi*0.01^2*Cos45
fi = 2.22*10^-6 wb

case 3:
fi = B*A*CosA
fi = 0.01*pi*0.01^2*Cos90
fi = 0 wb
