Consider the circular motion of a positively charged particle in the plane of this paper, due to a constant magnetic field B~ which points out of the paper. Neglect the effect due to gravity. B B What is the direction of the orbital motion of the particle? 1. counterclockwise pham (vp7427) – Homework 9 - Magnets and magnetic fields – reilly – (54195) 2 2. Insufficient information 3. clockwise

the direction of the particle is anti clockwise.

Explanation:

We know that;

- It's a positive particle

- That it's moving in a circle in a magnetic field

- We know the direction of the magnetic field

We can deduce the direction of the magnetic force because it is moving in a circle.

So the force is pointing to the centre of the circle and that's what is keeping it in that circular motion.

Since we know the direction of the magnetic field and force, we can use right hand rule to figure out the direction of the particle since the particle is positive.

Using right hand rule, the thumb which is the particle is pointing anticlockwise. So the direction of the particle is anti clockwise.
