Magnetic Field B Flux Through a Surface Explained

AI Thread Summary
The flux of a magnetic field B through a surface quantifies the strength of the magnetic field over a specific area A, calculated using the equation magnetic flux = A * B. When the magnetic field is not perpendicular to the surface, the flux is adjusted by the angle of inclination, represented by the equation A * B * cos(theta). The discussion confirms that this explanation is accurate but raises considerations about more complex scenarios, such as non-planar surfaces or varying magnetic fields. The original poster's definition is deemed sufficient for a level 2 course. Overall, the explanation effectively covers the basic concept of magnetic flux.

I have been asked to explain what is meant by 'the flux of a magnetic field B through a surface' and to include the case where the field is NOT perpendicular to the plane of the surface.

This seems quite simple but i just wanted to check my definition with you guys

I have;

The flux of a magnetic field B through a surface is the the strength of the magnetic field over a given area A and is given by the equation magnetic flux=A*B

Where the field is NOT perpendicluar to the plane it is given by the inclined angle to the perpendicular and given by the equation A*Bcos(theta)

Is that pretty much it?
Hope so :)

That's OK, you are not saying anything incorrect. I am not sure though how complete your answer must be. For example, what happens when the surface is not a plane or when the magnetic field changes magnitude and/or direction from one point of the surface to the next. To get a better picture see the wikipedia article

The quation just says; Expalin what is meant by"'the flux of a magnetic field B through a surface' Include the case where the magnetic field is NOT perpendicular to the plane of the surface.
Its a level 2 course
 
You are fine with what you have then.
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Thread 'A bead-mass oscillatory system problem'
I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
