# You asked: How do you find the magnitude of a magnetic force?

Contents

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 the magnitude of a magnetic field?

Magnetic Force

1. The force is perpendicular to both the velocity v of the charge q and the magnetic field B. 2. The magnitude of the force is F = qvB sinθ where θ is the angle < 180 degrees between the velocity and the magnetic field.

## What is the formula of magnetic intensity?

The strength of magnetic field at a point can be given in terms of vector quantity called magnetic intensity (H). Where, H = nI. Unit of magnetic intensity is A/m and its dimensions are [L-1M0T0I1].

## What is the formula of magnitude?

The formula for the magnitude of a vector can be generalized to arbitrary dimensions. For example, if a=(a1,a2,a3,a4) is a four-dimensional vector, the formula for its magnitude is ∥a∥=√a21+a22+a23+a24.

## What is meant by magnitude of magnetic field?

The magnitude of the magnetic force between them depends on how much charge is in how much motion in each of the two objects and how far apart they are. … The usual way to go about finding the magnetic force is framed in terms of a fixed amount of charge q moving at constant velocity v in a uniform magnetic field B.

## What is the magnetic intensity?

: a vector quantity pertaining to the condition at any point under magnetic influence (as of a magnet, an electric current, or an electromagnetic wave) measured by the force exerted in a vacuum upon a free unit north pole placed at the point in question. — called also magnetic force.

## Can we see magnetic flux lines?

At each end of a magnet is a pole. These lines of flux (called a vector field) can not be seen by the naked eye, but they can be seen visually by using iron fillings sprinkled onto a sheet of paper or by using a small compass to trace them out.

## What is unit of magnetization?

The magnetic dipole moment acquired per unit volume is known as magnetisation. Its SI unit will be m3Am2=mA. Its dimension is [L−1M0T0I1].

## What is the right hand rule for magnetic force?

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.

## What are the properties of permanent magnet?

A good permanent magnet should produce a high magnetic field with a low mass, and should be stable against the influences which would demagnetize it. The desirable properties of such magnets are typically stated in terms of the remanence and coercivity of the magnet materials.

## What happens to a proton in a magnetic field?

Since the magnetic force is perpendicular to the direction of travel, a charged particle follows a curved path in a magnetic field. … The magnetic force is perpendicular to the velocity, so velocity changes in direction but not magnitude. The result is uniform circular motion.

## What is the magnitude of a force?

The magnitude of the net force acting on an object is equal to the mass of the object multiplied by the acceleration of the object as shown in the formula below. If the net force acting on an object is zero, then the object is not accelerating and is in a state that we call equilibrium.

## How do you find magnitude in physics?

The correct answer is magnitude 5.1, angle 79 degrees.

1. Apply the Pythagorean theorem to find the magnitude. Plug in the numbers to get 5.1.
2. Apply the equation theta= tan–1(y/x) to find the angle. Plug in the numbers to get tan–1(5.0/1.0) = 79 degrees.

## What is the magnitude of?

The size of something. The magnitude of a number (also called its absolute value) is its distance from zero, so. • the magnitude of 6 is 6. • the magnitude of −6 is also 6. The magnitude of a vector is its length (ignoring direction).
