How do you find the force between two magnets?

The most elementary force between magnets is the magnetic dipole–dipole interaction. If all of the magnetic dipoles that make up two magnets are known then the net force on both magnets can be determined by summing up all these interactions between the dipoles of the first magnet and that of the second.

What does the force between two magnets depend on?

Consider two objects. 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 direction of the force depends on the relative directions of motion of the charge in each case.

What happens if you force two magnets together?

When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another. This is similar to electric charges. Like charges repel, and unlike charges attract. Since a free hanging magnet will always face north, magnets have long been used for finding direction.

Where is the force of a magnet the strongest?

north pole
the closer the lines, the stronger the magnetic field (so the magnetic field from a bar magnet is strongest closest to the poles) the lines have arrowheads to show the direction of the force exerted by a magnetic north pole.

Where on a magnet is the magnetic effect strongest?

Magnetic pole, region at each end of a magnet where the external magnetic field is strongest. A bar magnet suspended in Earth’s magnetic field orients itself in a north–south direction. The north-seeking pole of such a magnet, or any similar pole, is called a north magnetic pole.

What material is most effective at reducing attraction between two magnets?

Copper has one of the lowest permeabilities. Permalloy is well known but Mu Metal is the best and about the highest permeable metal alloy known and also available as sheet metal. Multiple layers also helps reduce eddy currents from passing magnets.

Does putting 2 magnets together make them stronger?

Once a magnet is fully magnetised, it cannot be made any stronger as it is fully ‘saturated’. As more magnets are stacked together, the strength will increase until the length of the stack is equal to the diameter. After this point, any further magnets added will provide a negligible increase in performance.

What are the 7 magnets?

What Are the 7 Types of Magnets

• Neodymium iron boron (NdFeB) – Permanent magnet.
• Samarium cobalt (SmCo) – Permanent magnet.
• Alnico – Permanent magnet.
• Ceramic or ferrite magnets – Permanent magnet.
• Temporary Magnets – magnetized in the presence of a magnetic field.

Which pair of magnets have the strongest attraction between them?

The magnetic field generated by any magnet is always strongest at either pole. The magnetic force is equally as strong at both the north and south pole.

How to measure the force of two magnets?

In this experiment you’ll measure the force F newtons ( N ) required to press two rectangular magnets together as a function of the distance between the centers of the magnets. One magnet will be fixed to a block and the other magnet will be suspended above. A cup is balanced on top of the upper magnet.

How are magnetic forces used in an experiment?

In this experiment, you will investigate the magnetic force between two current carrying wires. One wire will be a coil of 10 turns and the other will be a coil of 38 turns. The 10-turn coil will be taped to one end of a pivoted balance beam. The beam pivots on two pins.

How does a wire loop create a magnetic force?

This wire loop is then placed into the permanent magnet assembly so the wire loop is perpendicular to the magnetic field but is not touching the magnets. Then, when a current flows through the wire loop, a magnetic force is created.

What’s the easiest way to do a magnet experiment?

Easy Magnet Experiment #4: The Jitters Place two rectangular magnets underneath the donut magnet. Gently pull on the donut magnet to release it from the magnetic field then let it drop and swing over the rectangular magnets. It will quickly be caught right back in the magnetic field and move quickly back and forth in a jitterbug dance.
