Answer:
The magnetic flux through the desk surface is [tex]6.6\times10^{-4}\ T-m^2[/tex].
Explanation:
Given that,
Magnetic field B = 0.42 T
Angle =68°
We need to calculate the magnetic flux
[tex]\phi=BA\costheta[/tex]
Where, B = magnetic field
A = area
Put the value into the formula
[tex]\phi=0.42\times10^{-3}\times1.7\times1.0\cos22^{\circ}[/tex]
[tex]\phi=0.42\times10^{-3}\times1.7\times1.0\times0.927[/tex]
[tex]\phi=6.6\times10^{-4}\ T-m^2[/tex]
Hence, The magnetic flux through the desk surface is [tex]6.6\times10^{-4}\ T-m^2[/tex].
