What is different about the magnetic poles of common refrigerator magnets and those of common bar magnets?

What is different about magnetic poles of common refrigerator magnets compared to those of common bar magnets? Refrigerator magnets have narrow strips of alternating north and south poles. A wooden pencil, on the other hand, does not have magnetic domains that will interact with a magnet.

Does magnetism change with size?

How does the shape of a magnet affect its magnetic field? Size is just one of the ways one can change the strength of a magnet. By reducing the electrical resistance, much higher amounts of electrical current can be put through the magnets, thereby generating a much stronger magnetic force.

Does magnetism depend on size?

Does the size of a magnet affect its strength? The short answer is yes, but only because the size of a magnet means that there are proportionally more domains that can align and produce a stronger magnetic field than a smaller piece of the same material.

When the same poles of two magnets whether north or south are placed close to each other they?

In other words, if you hold two magnets together so that like-poles are close together (two norths OR two souths), they repel.

What is the difference between north pole and south pole of a magnet?

Main Difference – North vs. South Pole. Magnets are objects that can either attract or repel other magnets. The main difference between north and south pole is that a north pole is attracted towards the south pole of another magnet while a south pole is attracted towards the north pole of another magnet.

What is the difference between magnetic and non-magnetic?

Substances that are attracted by a magnet are called magnetic substances. Example: Iron, cobalt, nickel, etc. Substances that are not attracted by a magnet are called non-magnetic materials. Example: Aluminium, copper, wood, etc.

Are larger magnets stronger than smaller magnets?

Q: Are bigger magnets stronger than smaller ones? A: Generally yes, but not always. A larger magnet made from the same material and shaped in the same way as a smaller one will be stronger.

What determines the size of a magnetic field?

The magnitude of the magnetic field (B) is more a function of the shape of the magnet than its size. For example, a 1/4″ cube (B444) has a Surface Field of 5754 Gauss. So does a bigger cube, such as a 1/2″ cube (B888), 1″ cube (BX0X0X0), or even a monster 2″ cube (BY0Y0Y0).

What happens if the south pole of another bar magnet is brought closer to the north pole of the magnet?

Answer: The end that faces the north is called the north-seeking pole, or north pole, of the magnet. The other end is called the south pole. When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another.

Which is colder the south pole or the north pole?

The Short Answer: Both the Arctic (North Pole) and the Antarctic (South Pole) are cold because they don’t get any direct sunlight. However, the South Pole is a lot colder than the North Pole.

Why don’t magnets move when placed close to each other?

It’s also why two magnets may move together if you set them near each other, but if you set them far apart nothing will happen. However, as two objects get far apart, the gravity between them goes down by a factor of four when you double the distance, but the magnetic force goes down by (at least) a factor of sixteen.

What is the difference between similar and unlike magnetic poles?

Similar magnetic poles repel and unlike magnetic poles attract each other. Magnetic forces are non contact forces; they pull or push on objects without touching them. Magnets are only attracted to a few ‘magnetic’ metals and not all matter.

How do magnets and gravity affect non-magnetic objects?

Some of those ‘non-magnetic’ things are attracted to magnets and others are repelled. By the way, only some ferrous materials are magnets, and only a few magnetic materials are ferrous. Both magnetism and gravity can affect objects at a distance. Both get weaker as the objects get farther apart.

What are the four forces that act on a magnet?

Field (non-contact) forces 1 gravitational force 2 magnetic force 3 electrostatic force 4 field forces 5 attraction 6 repulsion
