Magnetic Flux

The video tutorial begins with a brief introduction and a review of electric flux, including its definition, symbol, and equations. It then transitions to magnetic flux, explaining its similarities to electric flux, the symbol used, and the equations for calculating it. The units of magnetic flux, webers, are discussed, followed by a practical example using a circular loop of wire. The right-hand rule is introduced to determine the direction of the area vector. The tutorial concludes with calculations of magnetic flux in different orientations, emphasizing the impact of the angle between the magnetic field and the area vector.

What is the symbol used for electric flux?

• Uppercase Phi with subscript E

• Uppercase Phi with subscript B

• Lowercase phi with subscript E

• Lowercase phi with subscript B

In the example with the bike wheel rim, what is the direction of the area vector when the loop is horizontal?

• To the left

• Downwards

• Upwards

• To the right

What is the magnetic flux through the loop when the plane of the loop is parallel to the magnetic field?

• Infinite

• Minimum

• Zero

When the loop is vertical, what is the angle between the magnetic field and the area vector?

• 0 degrees

• 45 degrees
