Magnetic and Electric Field Lines

AI Thread Summary
Magnetic and electric field lines visually represent the characteristics of these fields. The spacing of the lines indicates field strength, with farther apart lines signifying weaker fields. For electric fields, lines radiate outward from positive charges, while magnetic fields exhibit closed loops. The direction of the field at any point is tangent to the field line. Understanding these properties helps in analyzing the behavior of electric and magnetic forces.

Homework Statement



Magnetic and electric field lines are visually defined by field lines. Give three points to explain how the field lines can be used to describe the characteristics of these fields.

Homework Equations



(Not sure if needed to describe) Fm = qvBsin0, Fm = IlBsin0

The Attempt at a Solution



Farther apart lines = weaker fields?

Positive charge = fields radiate from a point charge

At every point on line, direction of field is tangeant

The equations are not necessary. Seems okay to me.

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...
