Using Ampere's Law in finding H (magnetic field intensity)

AI Thread Summary
To find the magnetic field intensity H in the given conducting slabs, Ampere's Circuital Law should be applied using a rectangular loop around each slab. The slabs carry uniform current densities of 10 A/m^2 in opposite directions, affecting the magnetic field in the specified z regions. The Biot-Savart Law may also provide insights into calculating H based on the current distribution. It's recommended to refer to textbook examples for guidance on applying Ampere's Law effectively. Understanding these principles will aid in solving the problem accurately.

Homework Statement



Let the regions 0 < z < 0.3 m and 0.7 < z < 1.0 m be conducting slabs carrying uniform current densities of 10 A/m^2 in opposite directions. Find H (the magnetic field intensity) and different z positions.

Homework Equations



Biot-Sarvot Law: H = ∫ (I dL X r)/ (4∏R2)

Ampere's Circuital Law: ∫ HdL = I

The Attempt at a Solution



I am guessing we have to apply ampere's law to each slab, in a rectangular loop. The slabs extend infinetly in the y and x axes. But I got no clue on exactly how to apply this law :( Any help would be appreciated as this my first post here.

Thanks!

Good idea. Surely your textbook has examples of how to apply Ampere's law.

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...

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
