What Is the Direction of Induced Current in Copper and Glass Tubes?

AI Thread Summary
When a magnet is dropped through a copper tube, it induces a clockwise current due to the changing magnetic field, following the left-hand rule. In contrast, no induced current occurs in a glass tube since it is non-conductive. The correct answer to the question is b) clockwise for the copper tube and no induced current for the glass tube. The discussion confirms the understanding of electromagnetic induction principles. This highlights the difference in conductivity between copper and glass in relation to induced currents.

Homework Statement


A magnet is dropped down each the copper and glass tube. What direction is the induced current in the copper and glass tube respectively?

a)clockwise, clockwise
b)clockwise, no induced current
c)counter clockwise, clockwise
d)counter clockwise, no induced current


Homework Equations


None are necessary.


The Attempt at a Solution


I think the answer is b) clockwise, no induced current. Using the left hand rule the direction of the magnetic field in the copper tube is upwards and the direction of the current is clockwise. Current cannot be induced in a glass tube. Am I right?

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 hanging 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...
