# Quick Answer: What is the magnetic force on the proton?

Contents

## How do you find the magnetic force of a proton?

The direction of the force vector can be found using the “right hand rule”. The direction of the motion of the protons is to the right, and so imagine your right index finger pointed in that direction. The magnetic field vector is pointed downward right, so curl your fingers down.

## What is the magnitude of the magnetic force on the proton?

(a) A proton, traveling with a velocity of 4.5 x 106 m/s due east, experiences a magnetic force that has a maximum magnitude of 8.0 x 10-14 N and a direction of due south.

## 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 formula for calculating the force of a magnetic field?

The force on a current-carrying wire in a magnetic field is F = IlB sin θ. Its direction is given by RHR-1.

## 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.

## Do magnets have to touch in order to experience magnetic force?

The force exerted by a magnet is called The push or pull of magnetism can act at a distance, which means that the magnet does not have to touch an object to exert a force on it. … You may be familiar with magnets attracting, or pulling, metal objects toward them. Magnets can also repel, or push away, objects.

## Does a moving proton create a magnetic field?

Magnetic fields are produced by moving electric charges. Everything is made up of atoms, and each atom has a nucleus made of neutrons and protons with electrons that orbit around the nucleus. Since the orbiting electrons ≠are tiny moving charges, a small magnetic field is created around each atom.

## 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.

## Why does magnetic field depends on moving charges only?

What is the mechanism by which one magnet exerts a force on another? The answer is related to the fact that all magnetism is caused by current, the flow of charge. Magnetic fields exert forces on moving charges, and so they exert forces on other magnets, all of which have moving charges.

## What will happen when electrons are immersed into a magnetic field?

In a magnetic field the force is always at right angles to the motion of the electron (Fleming’s left hand rule) and so the resulting path of the electron is circular (Figure 1). … Charged particles move in straight lines at a constant speed if projected into a magnetic field along the direction of the field.

## Why is force perpendicular to magnetic field?

The superficial answer is simply that the Lorentz (magnetic) force is proportional to v×B, where v is the particle velocity and B is the magnetic field. Since the vector cross product is always at right angles to each of the vector factors, the force is perpendicular to v. … It sees no force, since the wire is neutral.25 мая 2013 г.

## What is the relationship between magnetic force and distance?

Magnetic force obeys an inverse square law with distance. The equation for magnetic force is similar to Coulomb’s Law (if you are familiar with it). But the key point is that the force is inversely proportional to the distance squared (i.e. it obeys an inverse square law with distance).

## How do you calculate the force of a wire?

The equation for calculating the force on a wire is Force (N) = magnetic flux density (T) × current (A) × length (m) or, in short F = B I L.

## Is magnetic force stronger than electric force?

the attractive magnetic force between 2 electrons moving parallel to each other near the speed of light is nearly equal to the repulsize electric force between them.
