What do N and S mean on a magnet?

Figure 2. One end of a bar magnet is suspended from a thread that points toward north. The magnet's two poles are labeled N and S for north-seeking and south-seeking poles, respectively.

Is N or S positive in a magnet?

Often times, the poles are often referred to as being positive or negative. Generally, the south pole is termed positive, and the north negative.

What are magnetic lines from N to S?

Magnetic field lines are the imaginary lines around a magnet which gives us the pattern of magnetic field of the magnet. These lines don't start or end. They form a closed loop. They flow from North pole to South pole outside the magnet, while they flow from South pole to North pole inside the magnet.

What does the N stand for on a bar magnet?

The end that points to the north is called the north or N pole, and the end that points to the south is the south pole or S pole. The magnetic line of induction of the bar magnet is a closed curve that does not cross and goes out of the N pole of the magnet and back to the S pole.

What does N and S indicate?

What does N52 magnet mean?

An N52 magnet is a neodymium magnet that contains an energy product or (BH)Max of 52MGOe (Mega-Gauss Oersteds). The “N52” is an abbreviation referring to the strength of this magnet.

What is the difference between N42 and N52 magnets?

N42 grade offers a high performance at an economical price. Grades above N42 tend to be more expensive and the rise in price can be disproportionate to the increase in performance. An example is N52 grade which is 20% more powerful than N42 grade and yet can be twice the price.

What is the difference between N52 and N42 magnets?

N50 and N52 magnets may be stronger, but their maximum working temperature is limited to 60 ℃, or 140°F. Comparatively, N42 neodymium magnets have a maximum working temperature of 80 ℃, or 176°F. This makes them a better choice for applications where higher working temperatures are involved.

Which side of magnet sticks to metal?

Both the north pole or south pole of a magnet are equal in holding power and both will stick to magnetic material such as steel or iron.

What is an example of magnetic S?

Magnetic poles always exist in pairs. Examples of magnetic substances include iron, nickel, cobalt, stainless steel, and many rare earth metals. Diamagnetic materials like copper and gold are weakly repelled by a magnetic field. Paramagnetic materials like calcium and aluminum are weakly attracted by a magnetic field.

Can a magnet be broken into N and S poles?

No worries!

Which magnet is stronger N35 or N52?

There are eight different standard grades of neodymium magnets typically used in commercial applications today ranging from N35 to N52. Neodymium magnets are graded by their maximum energy product (BH)max with N52 grade neodymium providing the greatest magnetic performance and N35 being the weakest.

What is the strongest grade of magnet?

Neodymium magnets are by far the strongest type of permanent magnet available.

Why are neodymium magnets so cheap?

The relatively low rare earth content (12% by volume, 26.7% by mass) and the relative abundance of neodymium and iron compared with samarium and cobalt makes neodymium magnets lower in price than samarium-cobalt magnets.

What is the best grade of neodymium magnets?

Grades of Neodymium

As a very general rule, the higher the grade (the number following the 'N'), the stronger the magnet. The highest grade of neodymium magnet currently available is N52. Any letter following the grade refers to the temperature rating of the magnet.

Which is stronger rare earth magnets or neodymium?

Rare earth magnets are made from rare earth elements found on the periodic table. Neodymium magnets are the strongest rare earth magnets and the strongest magnets in the world. What is the strongest type of magnet? Neodymium magnets are the strongest magnets in the world.

Which magnet is better ferrite or neodymium?

A rare earth or neodymium magnet is the most powerful of any permanent magnets and is around 2-7 times stronger than a regular or ferrite magnet. It can lift more than any other type of magnet of the same size.

Which side of a magnet is negative?

Poles: There are two poles, positive and negative, which are located at the ends of the magnet. The north pole has a positive charge and the south pole has a negative charge, unlike electric charges, the poles can be separated.

Can you change the polarity of a magnet?

The polarity of a magnet actually can be reversed, but the process can take several tries before it is finally successful. In order to reverse the polarity of a regular magnet, you need the power of a battery and a coil of copper. For an electromagnet, you will just switch the wires around on the inside.

Are compass needles tiny magnets?

A compass allows us to observe the direction of a magnetic field: compass needles are just little magnets that are free to rotate. Normally, compasses respond to Earth's magnetic field, orienting themselves parallel to magnetic field lines.

What is the rarest magnet?

Neodymium Magnets (commonly known as Neodymium Iron Boride, NdFeb, or Neo magnets) are the most powerful Rare-Earth magnets available today.

How can you tell how strong a magnet is?

The maximum energy product of a magnet is measured in Mega Gauss Oersteds (MGOe). This is the primary indicator of a magnets 'strength'. In general, the higher the maximum energy product value, the greater the magnetic field the magnet will generate in a particular application.

How do you know if a magnet is neodymium?

Neodymium Magnet Grades

Magnets with higher N grades will typically be more brittle than those with lower numbers. The proceeding 'N' refers to neodymium and some magnet grades also feature suffixed letters indicating the coercivity. Common grades include neodymium magnets N52, N50, N48, N45, N42 and N35.

How many pounds can a N52 magnet hold?

N52 magnets, stronger than N50 Magnetized through thickness 3/4" Pull force: over 76 lbs.
