# How can 2 magnets demonstrate magnetic force?

Contents

Place one magnet on one pan of the scale with the poles oriented vertically. Then balance the scale by adding mass to the other side. … If you placed the two magnets so that opposite poles are facing each other, the force will be attractive and you will need to add more mass to the opposite side of the scale.

## How do 2 magnets work?

The arrows always start at the magnet’s north pole and point towards its south pole. When two like-poles point together, the arrows from the two magnets point in OPPOSITE directions and the field lines cannot join up. So the magnets will push apart (repel).

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

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
3. The direction of the force is given by the right hand rule.

## What causes the magnetic force of two magnets to repel each other?

This is because when the two magnets of like poles are kept facing each other the lines of forces are in opposite directions. So the like poles repel each other. When the unlike poles of a bar magnet face each other the magnetic lines of force are in the same direction and hence unlike poles attract each other.

## Can you force two magnets together?

Yes, stacking multiple magnets together can make them stronger. Two or more magnets stacked together will exhibit nearly the same strength as a single magnet of the combined size.

## When magnets are the force of magnetism is stronger?

The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole when compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center.

## Is the force between two magnets a contact force?

Magnetic forces are non contact forces; they pull or push on objects without touching them.

## How do you describe magnetic force?

magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. … The magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other.

## What is the example of magnetic force?

Examples of magnetic force is a compass, a motor, the magnets that hold stuff on the refrigerator, train tracks, and new roller coasters. All moving charges give rise to a magnetic field and the charges that move through its regions, experience a force.

## What causes magnetic force?

Magnetism is the force exerted by magnets when they attract or repel each other. Magnetism is caused by the motion of electric charges. Every substance is made up of tiny units called atoms. … Their movement generates an electric current and causes each electron to act like a microscopic magnet.

## How do two magnets interact with each other?

The two magnetic forces are interacting! All magnets have a north-seeking pole, and a south-seeking pole. … The new magnet may attract or repel the suspended magnet. When opposite poles of the magnets approach, they attract each other.

## How does the magnetic force change when you add magnets?

By adding one magnet on to the other, e.g. stacking, the stacked magnets will work as one bigger magnet and will exert a greater magnetic performance. As more magnets are stacked together, the strength will increase until the length of the stack is equal to the diameter.

## Why does the magnetic force change when you add magnets?

The force depends on the distance between the magnets. The farther apart the magnets are, the weaker the force. When the magnets are touching one another, at distance = 0, the force will be approximately equal to the magnet’s listed Pull Force, Case 1.

## Can magnets demagnetize each other?

Self Demagnetization

If you store a bunch of magnets together or randomly rub magnets against each other, each will affect the other, changing the orientation of the magnetic dipoles and lessening the net magnetic field strength. A strong magnet can be used to demagnetize a weaker that has a lower coercive field.
