Concept explainers

Rotational Equilibrium And Rotational Dynamics

In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics.

Equilibrium of Forces

The tension created on one body during push or pull is known as force.

Question

**Magnetic Induction in a Moving Rod**

A metal bar is in electrical contact with metal rails as it slides to the left (assume the rails and rod form a complete loop). The rod is moving to the left within a uniform magnetic field that points out of the screen.

**Question:** What is the direction of the induced current (if any) in the rod?

**Diagram Explanation:**

- The diagram shows a rectangular setup with a rod that can slide along two rails.
- The magnetic field (\(\vec{B}\)) is represented by blue dots, indicating it is directed out of the screen.
- The rod is depicted with a green arrow (\(\vec{v}\)), showing its velocity to the left.
- Distance \(a\) is shown between the two rails.

**Answer Choices:**
- There is no induced current.
- Up
- Down

Using electromagnetic principles, determine the direction of the induced current considering the given magnetic field and rod movement.
