Write an expression in a vector form for the Lorentz magnetic force `vecF` on a charge Q moving with velocity `vecV` in a magnetic field `vecB`. What is the direction of the magnetic force?

Explanation

To solve the problem, we need to derive the expression for the Lorentz magnetic force in vector form and determine its direction. Let's break this down step by step.

### Step 1: Understanding the Lorentz Force
The Lorentz force is the force experienced by a charged particle moving in a magnetic field. It is a combination of electric and magnetic forces, but here we will focus on the magnetic component.

### Step 2: Writing the Expression for Lorentz Magnetic Force
The expression for the Lorentz magnetic force \( \vec{F} \) on a charge \( Q \) moving with velocity \( \vec{V} \) in a magnetic field \( \vec{B} \) is given by:
\[
