Magnetic flux. Dont know where to start

AI Thread Summary
Magnetic flux through a circular area can be calculated using the formula Φ = B * A * cos(θ), where B is the magnetic field strength, A is the area, and θ is the angle between the magnetic field and the normal to the surface. For a radius of 7.90 cm, the area is approximately 0.00195 m². When the magnetic field is perpendicular to the surface (+z direction), the flux is maximized at 0.223 T. When the field is at an angle of 52.8 degrees, the flux is reduced due to the cosine factor. For a field pointing in the +y direction, the flux is zero since the angle between the field and the normal is 90 degrees.

Homework Statement


A circular area with a radius of 7.90cm lies in the x-y plane.
A. What is the magnitude of the magnetic flux through this circle due to a uniform magnetic field B = 0.223T that points in the +z direction?
B.What is the magnitude of the magnetic flux through this circle due to a uniform magnetic field B = 0.223T that points at an angle of 52.8∘ from the +z direction?
C.What is the magnitude of the magnetic flux through this circle due to a uniform magnetic field B = 0.223T that points in the +y direction?

i don't even know where to start with this, I am completely overwhelmed

You should look in your book for the definition of magnetix flux. If you ll understand the definition it would be easy to answer all 3 questions. The answer to each question is no more than a line.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
