At the equator, the direction of Earth's magnetic field is horizontal and to the north, and the magnitude is 3.5 ×10-5T.

Part A: What is the magnetic flux through a circular loop of radius 0.26 m , lying flat on the ground at the equator?

Φ =  Wb  

Part B: What is the magnetic flux through the loop of radius 0.26 m balanced on its edge on the ground at the equator, when the axis that runs perpendicular to the plane of the loop points northwest?

Φ = Wb  

Part C: What is the magnetic flux through the loop of radius 0.26 m balanced on its edge on the ground at the equator, when the axis that runs perpendicular to the plane of the loop is points due north?

Φ = Wb  

Part D: hat is the magnetic flux through the loop of radius 0.26 m balanced on its edge on the ground at the equator, when the axis that runs perpendicular to the plane of the loop is points to the west?

Φ = Wb
