I'm not sure about quarters in particular.
I do know that the British 1 and 2 pence coins used to be made of copper, a non-magnetic element. However recently the price of copper rose so much that the 1 and 2 pence cions were worth more than 1 or 2p. To remedy the situation the coins are now made of copper-plated steel. Steel is magnetic, hence the coins are.
In short I would guess it is because some quarters are made of magnetic metals like steel and nickel whereas other are not.
US quarters are not typically magnetic. Quarters are made of a combination of metals, including copper and nickel, which are not magnetic.
U.S. quarters are made of copper and nickel so they're not magnetic. But you did try to use a magnet on one to find out, of course.... Canadian quarters are made of nickel or steel depending on their age, so they are magnetic.
cause they are broken in half..
Originally, chalkboards were made of slate stone and were not magnetic. Some modern chalkboards today are magnetic. Also growing in popularity is the whiteboard, some of which are also magnetic.
Some staplers have small magnetic strips to help keep staples in place, but in general, staplers are not inherently magnetic.

Quarters are made of non-magnetic materials like copper and nickel, which do not have magnetic properties. Therefore, a quarter will not stick to a magnet because there are no magnetic forces attracting the two objects together.
They need some quarters.
Coins made of steel, iron or nickel would normally be magnetic. Exceptions are alloys, where the exact composition determines whether the charges of the atoms align (there are magnetic and non-magnetic variants of stainless steel).During World War II, US pennies were made of zinc-plated steel, and hence were magnetic. US nickels (5 cents) are 75% copper and 25% nickel, and are not magnetic, and neither are the "clad" copper-sandwich coins or the "gold" dollar coins (which are brass).Canadian nickels have been made of magnetic alloys several times, most recently 99% nickel from 1954 to 1981, and coated steel since 2000. From 1982 to 1999, Canada used the same copper-nickel alloy that US nickels are made of.
Some can be magnetic but the answer is
Peggy had three times as many quarters as nickels. She had $1.60 in all. How many nickels and how many quarters did she have?
You think the rarest would be when they made some of the first US quarters in our history.

There are 400 quarters in 400. If you would like to convert quarters to some other unit of measure you need to say what you want to convert into, like dollars or dimes or pounds.
Some are
They are arranged randomly so ultimate magnetic effect is zero. But in some material they do not cancel and have some +ve or -ve value.
