## What is the relation between magnetic field and velocity?

The magnetic force is perpendicular to the velocity, and so velocity changes in direction but not magnitude. Uniform circular motion results. The component of the velocity parallel to the field is unaffected, since the magnetic force is zero for motion parallel to the field.

## How do you find the velocity of a magnetic field?

Magnitude of the Magnetic Force. The magnetic force on a charged particle q moving in a magnetic field B with a velocity v (at angle θ to B) is F=qvBsin(θ) F = qvBsin ( θ ) .

**How do you find magnetic force with velocity and magnetic field?**

Magnetic Force

- The force is perpendicular to both the velocity v of the charge q and the magnetic field B.
- The magnitude of the force is F = qvB sinθ where θ is the angle < 180 degrees between the velocity and the magnetic field.
- The direction of the force is given by the right hand rule.

### How do you find the velocity of a magnetic field with charge?

We are given the charge, its velocity, and the magnetic field strength and direction. We can thus use the equation F = qvB sin θ to find the force.

### What is E in F qE?

This means that. The force experienced by a charge “q” placed in a magnetic field if intensity “E” is product of magnitudeof charge that is q and electric field intesity E. Mathematically expresed as. F=qE. Physics.

**What is the right hand rule for magnetic field?**

We can remember this diagram using the right-hand rule. If you point your pointer finger in the direction the positive charge is moving, and then your middle finger in the direction of the magnetic field, your thumb points in the direction of the magnetic force pushing on the moving charge.

#### How do you find the magnetic field with the right hand rule?

The right hand rule states that: to determine the direction of the magnetic force on a positive moving charge, point your right thumb in the direction of the velocity (v), your index finger in the direction of the magnetic field (B), and your middle finger will point in the direction of the the resulting magnetic force …

#### What does F BIL stand for?

F = BIL (f=force, b=magnetic field, i=current, l=length of conductor)

**What is qE formula?**

In the physics equation, F=qE, where E is the electric field, q is the charge, and F is the force that the electric field exerts on this charge, does the charge, q, by itself, have a direction associa | Study.com.

## What formula is F qE?

The actual force on a particle with charge q is given by F = qE. It points in the opposite direction of the electric field E for a negative charge. We calculate the electric field produced by a charge distribution using a set of equations called Maxwell’s equations.
